Ultra High Frequency (UHF) Tags are becoming more popular for solving difficult RFID problems and meeting business needs across various industries. However questions surrounding High Frequency (HF) and Ultra High Frequency or UHF tags remain. Many still wonder whether HF or UHF tags are the best solution for meeting business goals. To understand why UHF Tags are finally gaining popularity one must first understand what UHF Tags are, the differences between HF and UHF tags and applications where UHF Tags have been successfully deployed.

UHF Tags vs. HF Tags

Up until now HF Tags have been viewed as a more reliable and proven technology. However recent developments established that UHF tags are equally as reliable and often times can offer better performance across many applications. To understand why that is, we must first understand the difference between HF and UHF Tags.

HF and UHF Tags operate at different frequencies. The maximum range for HF tags is 13.56 MHz and the maximum read range is about 3 feet. Meanwhile UHF Tags operate in the 858 to 930 MHz frequency band and can have a read range of 30 feet (while there are tags with a longer read range, 30ft are an average).

HF Tags are considered more “mature” tags, since they have been around for longer. While UHF tags are dominant technology for supply chain applications, it is believed that due to their “maturity” and a short read range HF tags are a better choice for item level or near-field applications. However over the past years it has become apparent that UHF Tags are equally as reliable as HF tags and often can offer better performance. UHF tags do not need to be near field tags to be read at a close range. Unlike HF tags, UHF tags can be read both at close and long ranges: a 30 ft. tag can also be read from an inch away. Because of their versatile read range, UHF tags can be optimized for various applications and be processed at various read distances. UHF Tags are perfect for work-in-process applications including, inventory tracking, anti-counterfeit applications, identification applications and many more. Because UHF Tags can provide the range and coverage users need, UHF tags are perfect for applications where a “universal” tag is necessary or a tag that can be read at both long and short distances.

Additionally, HF tags are not an option where a longer read range is required. Therefore it is important to consider future applications and extensions of RFID uses when planning on implementing an HF RFID System.

Advantages of UHF Tags

There are several advantages to using UHF Tags, the two most relevant are cost and performance. In the section above we touched upon how UHF Tags have a longer read distance; however we have yet to explain the difference in speed. The speed at which UHF tags may be read and the distance over which UHF tags may be read are usually higher when compared to HF tags. Additionally, due to mandates to their supplier to use UHF tags for their supply chain tracking, from giants such as Wal-Mart and Gillette it is believed that UHF Tags will be cheaper. The idea is that as UHF tag production volume increase, cost will decrease. Furthermore it is suggested that as UHF tags become more popular in item level tagging and the production numbers will reach billions, tag prices will plummet.

While both of these factors suggest operational benefits to implementing a UHF RFID system, there are still misconceptions that need to be cleared. The next section deals with myths and misconceptions if UHF Tags.

Misconceptions about UHF Tags

While UHF tags can obviously offer a versatile read distance, many believe there are drawbacks to UHF Tags. For a long time it was believed that

1. UHF Tags could not function on/in water or metal

2. UHF Tags could not provide shorter read range

3. UHF Tags are too large and are inappropriate for applications where a smaller footprint is necessary

This section is delegated to reexamining these misconceptions and myths about UHF Tag.

1. UHF Tags cannot function on or in liquids or metals.
It is well proven that HF tags perform reliably and accurately on liquids and metals. However, for a while it was believed that UHF tags cannot function on/in liquids. The later claim is untrue: UHF tags perform equally well (if not better) on both liquids and metals. UHF Gen 2 Tags not only work on liquids they actually work in containers that are filled with liquids. In 2009 an RFID tag manufacturer demonstrated that a UHF Tag can, not only work on containers containing liquids but in liquids as well, by reading a UHF Tag placed inside a Gatorade bottle.

Additionally UHF tags not only work on metal, but these tags actually take advantage of the metal background, utilizing it to increase performance. For example, Boeing chose to identify aircraft parts with UHF Tags to streamline maintenance and pre – flight inspection processes. Boeing used a mount – on – metal UHF tag to identify metal objects. Additionally, RCD Technology’s Sentry Family of Asset tags are all mount on metal UHF Tags, specifically designed for superior performance on metal surfaces.
In short, UHF tags are flexible and can be designed to achieve the best performance required on metal and on – or in – liquids.

2. UHF Tags do not provide contained read range, required for item level tracking.
UHF Tags can provide a full spectrum of ranges required, from near field ranges as small as an inch away to 50+ft. Read range is not strictly determined by the frequency. UHF Tag inlays designed to have a shortened read range will be as good (if not better) as HF tags. Antennas can be designed to have a short, long or complete read ranges. Unlike HF Tags, UHF tags allow for flexibility in read range, tags can be designed to function in near and far field applications.

3. UHF Tags are too large and are inappropriate for applications where a smaller footprint is necessary
UHF Tags do not have size constraints. UHF Tags can be designed based on a footprint. For example RCD Technology developed a UHF Tag; with a footprint small enough to be placed on servers that have limited space (36.3mm x 10.9mm x 2.8mm). Additionally, medical UHF labels can be found as small as 9 mm in size. UHF tags provide the flexibility to meet customers’ needs, from short range tags to tags small enough to fit in the cap of a vial to large tags that require robust performance in the longest of read ranges.

Conclusion

As one can see from this brief, UHF Tags are the right choice for most applications. While UHF can offer the same effective uses as HF, the reverse is not true. UHF tags can be read at a long and short distances, while HF tags are limited to a very short read range. UHF tags are easily customized to meet application specific goals and can be read on/in water, on metal, and can vary in size. Additionally UHF tags have been implemented in many supply chains and business in many difficult applications. While HF may be the more “mature” technology, unlike UHF tags, they do not have the properties necessary to meet today’s evolving business needs.

What is an RFID Enabled Wristbands?

In simple terms, RFID wristband systems contain two parts: a tag and a reader. An RFID tag embedded in the wristband contains an antenna; the majority of these tags are passive. Passive RFID tags are small data transponders that are powered by the radiation received from a querying RFID reader – these tags “wake – up” when irradiated by the reader.  Active RFID wristbands contain batteries and can send signals to readers. Readers can be mounted on walls, doorways, ceiling or be hand held.  A lost child wearing a barcode wristband in RFID wristband in an amusement park can be located by the reader infrastructure which then transmits that location information to his/her parents.

RFID Wristbands in Healthcare:

There are many applications for RFID technology in healthcare. RFID wristbands specifically can be used in patient safety applications. These applications can provide patient tracking and identification services through the use of RFID wristbands. Additionally the use of RFID wristbands in healthcare can improve resource utilization and expedite patient admission process within all hospital departments. Due to the lack of real-time data, majority of the hospitals find it hard to keep track of their patients’ whereabouts while the hospital staff is on the move, thus leading to delays in patient admission from the emergency department.   By assigning RFID wristbands to patients at the point of admission, recording patient information on these wristbands and strategically placing RFID readers throughout the hospital, patients can be located and identified while moving freely around the hospital, thus decreasing delays throughout the hospital.

In addition, RFID wristbands can be used to record patient information to correctly identify patients. Incorrect identification of patients can lead to incorrect drug administration, execution of undesired procedures, misfiling of results and medical documentation and can cause general delays.  RFID enabled wristbands can, not only store patient information, but can have read and write capabilities as well. Usually, nurses and hospital personnel take notes by hand and then enter them into databases, leaving room for human error and causing general delays in hospital proceedings.  With RFID enabled wristbands patient information, can be retrieved from the database via a wireless network by getting RFID enabled handheld devices in the vicinity of the wristbands. Hospital personal can obtain information on their patient instantly through patient’s wristband. With the use of RFID enabled wristbands doctors and nurses can monitor patients’ in real time, decrease mistakes and allow for a faster patient admission and treatment.

Some hospitals are already employing RFID enabled wristbands to help them track and identify patients. In 2003, The Albert Einstein Healthcare Network in Philadelphia, PA deployed a passive RFID identification tracking system. Since the deployment the hospital increased emergency department traffic flow by 24% and decreased the number of patients leaving before receiving care by 3%. ¹

RFID Enabled Wristbands in the Entertainment Industry

RFID wristbands can have various applications in the entertainment industry. Amusement parks, cruises, concerts and festivals could all benefit from RFID wristband deployment. RFID wristbands in amusement parks can provide customers with convenience and security. According to some studies, over 27% of all families that visit an amusement park loose one of their children while there. ² With the use of RFID wristbands parks can prevent children from being lost. RFID wristbands assigned to park goers at the point of ticket purchase, can store basic information such as name, telephone number and address of the person wearing the wristband. Parents with lost children could go to park administration and retrieve their child’s location.  Paramount’s Great American in Santa Clara, CA is a perfect example of an amusement park using RFID enabled wristbands to track park goers. Great American attendees get RFID wristbands with his/her name. One of many antennas scattered throughout the park –whichever is closest to the person at any given moment –reads the wristband and sends the information to the park’s administration. Parents who lose their children can go to any service kiosk, wave their own wristband, and bring up maps showing their kids’ locations. ³

Cruises, concerts and festivals could all benefit from similar RFID wristband applications. By utilizing RFID enabled wristbands, these ventures can not only track their customers but also provide them with convenience and security.

Royal Caribbean Oasis did just that, when it set sail in December 2009. The world’s largest cruise ship provided its customers with RFID wristbands that not only offered families and groups a way to track their members, but to also allowed users to make reservations at restaurant’s and spas. The application used Wi-Fi based RFID tags in wristbands and Apple iPhones. The location information was transmitted to the iPhone user to send alerts, to those wearing wristbands. This allowed for users to move freely about the cruise ship without worrying about their family members being lost.  ⁴ Live sector can also benefit from RFID wristband deployment. By storing bank account information on RFID enabled wristbands, attendees will not need to bring their debit cards, cash, and credit cards to the venue, therefore eliminating theft that occurs at concerts, sporting events and other similar events. Similarly, medical information can be stored on RFID wristbands, therefore upgrading safety for individuals in case of an emergency.  Additionally, RFID enabled wristbands allow administration personal to monitor the crowds. By scanning wristbands by readers that contain all of the information of all the wristband holders attending, and sending this data wirelessly to a server, crowds can be monitored and controlled in real time. In 2004, South by Southwest  (SXSW), a music festival held annually in Austin, Texas, used RFID wristbands to prevent counterfeiting of wristbands, eliminate over – crowding and to increase public safety at their events. ⁵

RFID Wristband Application in Defense

RFID enabled wristband applications vary when it comes to defense. These wristbands can be used to track wounded in warfare, track soldiers on battlefields, help families track relatives and identify victims during natural disasters. In 2007, U.S. Navy used RFID enabled wristbands to track and identify the wounded naval officers arriving at the field hospitals in Iraq. By employing RFID wristbands and satellite communication, medical personnel could better plan for arriving casualties. Additionally, the U.S. military has been considering using RFID to track soldiers on the battlefield to warn and monitor soldiers who are going in and out of chemical or biological hot zones. ⁶

Some companies have been employing RFID wristbands to help families prevent their loved ones, who are at risk, from wandering away from the house. If an individual wearing the wristband approaches a door, an alarm sounds. This application is perfect for individuals suffering from Alzheimer’s or similar conditions. ⁷

Additionally, the state of Texas used RFID wristbands to track victims of hurricane Ike and Gustav. In 2008, the state’s division of Emergency Management employed RFID wristbands to evacuate 34,800 residents. ⁸

Moving Forward

RFID wristbands can be used across many industries, and in various applications. However, the same holds true regardless of the industry or the application: RFID wristbands are becoming the standard in people identification and tracking. RFID enabled wristbands are used in healthcare, defense, entertainment industries and even some schools are starting to employ RFID to track student attendance. While the cost of RFID wristband systems may seem daunting, the system’s ability track patients in hospitals, cut down cost of counterfeit tickets at festivals, increase security and track wounded is a major plus.

Today, the largest RFID application aids companies and governments in supply chain management. RFID is being used to manage products through production, distribution and retail. Manufacturers can especially benefit from implementing RFID applications in supply chains because they can decrease costs associated with product tracking and inventory management and increase the accuracy and timeliness of inventory data. Experts say that early adaptors of RFID applications in supply chains have seen a significant increase in revenue.

RFID Applications in the Distribution Chain

RFID Applications can be used to monitor and manage the movement of the finished products throughout a supply chain.  RFDI tags can be attached directly to the items and materials or they can be attached to the containers that carry them.  Pallets, trailers, totes, carts, cargo containers, and reusable transport items can all be tagged. Readers placed throughout a facility can monitor movement and location of inventory, thus providing real time data.  This can be within a warehouse, a freight yard or within a retail location.

RFID applications in the supply chain enable more frequent and accurate inventory counts  RFID applications in the supply chain can also decrease costs associated with inventory counting

In addition, RFID applications in fleet management have demonstrated significant ROI.  RFID applications in fleet management enable a more cost-effective long-range tracking solution, global tracking of containers and cargo, reliable tracking of capital and inventory assets during transportation and increased security. By placing RFID tags on long range vehicles, trailers or other mobile assets, companies can gain visibility into their business’ assets’ utilization.

RFID Applications in Retail and Product Marketing

As in the distribution chain, RFID application in retail can greatly aid in reducing the cost of keeping accurate inventory data.  With fewer people and less time, retailers can keep accurate inventories.  Associates can spend more time providing service to customers rather than counting product.

RFID Applications in retail can greatly aid in ensuring proper product mix and availability are maintained for customers.  The accuracy of the real time inventory data that is provided by RFID applications, enables product marketing managers to ensure that hot selling items are properly stocked and to ensure replenishment order for these items are placed as quickly as possible.  Slow moving items can be quickly identified.  This allows product marketing managers to take corrective action to goose demand through promotional or advertising activity before a ‘fire sale’ is needed.  Thus RFID applications help product marketing managers maintain their margins.

RFID applications are, also, a significant aid in deterring theft in retail environments.  Items tagged with RFID devices can trigger alarms when they are removed from the store without being properly deactivated.  RFID applications have been successfully deployed for anti-theft purposes for several decades.

RFID Applications in Brand Protection

RFID applications can be used to protect brand identity by product marketing managers and to protect consumers from counterfeited products. RFID applications in anti-counterfeiting are, generally, aimed at high-value end consumer products.    The unique identification number on standard RFID tags can be used to verify the authenticity of the products to which they are attached.  These unique numbers combined with encryption algorithms can create authentication schemes that are extremely difficult for counterfeiters to circumvent.

RFID applications in anti-counterfeiting can be used in many industries, including pharmaceuticals, electronics, entertainment, retail, IT and many more. It is estimated that counterfeiting costs legitimate companies nearly $600B worldwide each year.  The payback even modestly successful anti-counterfeiting efforts can be very high.  RFID applications represent one of the most promising methods for countering this major problem.

By placing RFID tags on products at the point of manufacture, manufacturers can trace products throughout the supply chain. The pharmaceutical industry is creating an RFID application that will document the authenticity of their products at retail.  Not only will the products have a unique ID, but information about the chain of custody for the product will be stored on the RFID tag or in an associated database.   If the product is not properly tagged or the tag is not associated with the proper chain of custody – then you know the product is counterfeit.

While many anti-counterfeiting efforts are a large expense that most US companies face, RFID applications in anti-counterfeiting have a high ROI. By placing RFID tags on products at the point of manufacture, not only can products be traced throughout the supply chain, but it can also prevent counterfeit products from entering into the supply chain.

Conclusion

RFID application in the supply chain offer solutions when it is impractical to use other technologies or manual labor to collect data. RFID applications have many benefits; RFID applications can help in asset tracking, inventory and product management and provide solutions for anti-counterfeiting. Data collected to accomplish all these goals can provide suppliers and end users with the tools and information to make management decisions on the fly resulting in a better ROI.

There are two types of RFID product tags widely used in medical applications.  The first are HF (High Frequency) tags, which have short read ranges (up to 3 inches).  These tags can be used to tag tissue samples, blood and other critical fluids.  They work well in proximity to liquids and human tissue.  UHF RFID products have longer read ranges, but unless they are properly engineered, can be detuned by proximity to tissue, fluids and metals.   These RFID products are used to track and locate critical medical devices, manage inventories of medical items, and, sometimes for tracking and identifying patients.  The vast majority of these RFID products are compatible with worldwide standards and are easily deployed, because of their compatibility with widely available and competitively priced RFID readers.

One of the fastest growing applications for RFID product tags is to track of the pharmaceuticals and ensure their authenticity.  Application of RFID products to solve the problem of counterfeit drugs will dramatically increase the effectiveness of anti-counterfeiting efforts.  This will improve U.S. drug safety.

In the medical equipment field, RFID product tags can be used to track and locate medical devices. The use of RFID products on equipment and RTLS (Real time locating systems), enables hospital staff to rapidly locate critical medical devices.  When you need a defribulator, you need to locate it fast!  This enhances patient safety, and can reduce the amount of equipment investment needed.   Additionally these tags can be used to inventory equipment and consumables used in an operation, including scalpels, sponges, clamps and other surgical equipment.  At the end of an operation everything can be automatically accounted for.   Finally, applying RFID products to assets aids medical institutions in automating inventory management, reducing overhead and minimizing duplicate supplies of critical inventory.

RFID product tags can also be used in patient identification. These RFID products, in the form of ID cards, wrist or ankle bands, or labels applied to patient records, can greatly aid in assuring that the right procedures and medications are applied.  In addition, the RFID products enable data system to call the correct record for the patient who is scanned, and aids in the reducing errors associated with data entry.  Finally, RFID products can be used to track patient movements within a facility.  Patients with afflictions such as Alzheimer’s, can be tracked within a facility to ensure they do not get lost or enter an area where they might harm themselves.

Laboratories can use RFID products to track tissue or fluid samples.  As samples move through various preparation steps, they can be automatically tracked, reducing errors from data entry or mishandling. Samples that arrive at the pathologist for analysis will automatically have the patient record and the indication called to the computer screen to ensure proper association of the sample with the patient.

Finally, drug discovery firms are thinking of ways to use RFID products to automate the tracking and location of the millions of proprietary pharmaceutical compounds they have in their libraries.  These very valuable assets are difficult to inventory, but it is essential that it be done with a very high level of accuracy.  RFID products are perceived as an enabling technology for the automation of this task, but the high density and small size of these samples still present challenges.

The implementation of RFID products in the medical field has raised some concerns related to the confidentiality of medical information.  In the vast majority of cases, RFID product tags are used only as ‘license plates’ for the items they tag.  That is, they contain only an identifying number, and all the ‘human readable’ information about an asset, drug, tissue sample or patient, resides in a database on a computer that is linked to the RFID product via that license plate number.   Thus, security for the information resides in the data system, rather than in the RFID product or the transmissions between the RFID product and the RFID reader.  The FDA has outlined four components for ensuring medical information security.  Information must be kept confidential, it must be accurate and complete and it is available and accessible by following the prescribed process.  By storing this information in a computer based system, where security measures are already well established, the use of RFID products in medical processes does in not put at risk the security of this confidential information.

The implementation of RFID products in medical applications is reaching maturity in many areas.  Reduction of data entry errors, automation of work and information flows, improvement of asset and consumable inventories and better association of treatment plans with patients are all benefits of RFID products in the medical field.  The results are better patient outcomes and lower costs.  It is clear that established applications will continue to grow and that new applications will emerge for RFID products in the medical arena.

Types of Problems RFID Tags Can Solve

RFID is a  fundamental technology  used to solve many types of tracking, identification and security problems.  When used correctly, it allows real time monitoring and decision-making.   For example, RFID tags are applied to cargo containers and trailers.  When the containers enter and leave the freight yard, their contents are automatically logged into or out of inventory, and the owners of the cargo can be automatically updated regarding progress.  RFID tags user memory can, also,  be used as local information repositories, and can store service information on aircraft parts, or chain of custody information for pharmaceuticals.   RFID tags can, also, be used for security, to ensure tagged assets do not leave their assigned locations, or to ensure only properly authorized people enter secure facilities.

A November 2009 report from ABI Research suggests three areas where RFID will grow the most during the next five years.

• Fashion apparel
• Asset tracking and management – spare parts, tools, IT and medical assets, and rental-item management
• And active RFID tags – real-time location systems

Choosing the right RFID Tag

Many RFID applications can be satisfied with a standard RFID tag.  However, there are many use cases where a custom RFID tag is needed.  Applications where high or very specific RF performance is required will need a custom RFID tag.  If the tag will see extraordinary environmental or processing conditions, such as pressure washing, autoclaving or steam cleaning, a custom tag may be required.  It sometimes occurs that the tag must fit in an existing physical footprint on a product or container, and this will require a specially designed tag.  In people tracking applications, whether using cards, wristbands or tags, the interaction of the tag and the human body must be managed, and a custom tag will be needed to get the RF performance needed in the application.

If you should need a custom RFID tag design, be sure to choose a partner with a proven track record,  knowledge and experience in a wide variety of RFID applications and environments, and a solid network of partners.  The RFID tag design firm should be able to use your specifications to design and configure a custom RFID tag for optimal data collection and security.

Testing the Custom RFID Tag Design in the Application

Because communication with the tag is the essential data link that makes RFID deployment work, it is vital to test the tag in your application.   Conformance to specification is not always enough in custom RFID deployments.  Structures, vehicles, fluids and people as well as readers and tags can affect the performance of the system.  Many of these problems can be anticipated by a seasoned RFID tag designer, but it is always best to test in the ‘real world’ before rolling out a program.

RCD Technology has just released the newest addition to its Sentry family of asset tracking tags; the Sentry-M WW.  This patent pending, mount-on-metal asset tag is functional across the worldwide UHF frequency band of 860-960 MHz.  Developed in cooperation with Sun Microsystems, Inc. RCD is the first to deliver a true, global mount-on-metal tag with a footprint small enough for use on IT Assets.  It exceeds the FSTC performance guidelines in the North American, European and Japanese frequency bands making it ideal for source tagging of the OEM’s IT equipment. As a mount on metal solution, the Sentry-M WW can be used for tracking many metal assets, such as tools, metal containers or equipment.

Sun Microsystems plans to attach the Worldwide RFID tag to its products to help customers track their IT assets and comply with regional legal requirements. A large number of Sun customers are global and therefore require global solutions to run their businesses. A Sun customer in the financial services industry reported a 30% improvement in accuracy and a 60x reduction in time spent tracking assets after moving from bar-code to RFID.

The need for a worldwide tag stems from doing business in a global economy.  Today’s RFID asset tags are tuned for a specific region of the world, putting a global RFID asset tracking solution out of reach. The need for a worldwide tag is well justified as seen by the current global and volatile economies.  More than ever, we seek greater efficiency and less human error.   Additionally, customers are increasing their tracking and data collection requirements – either by choice or by government regulation.  OEM’s supply product to and from countries around the world.

Given these market, industry and operational dynamics, RCD’s Sentry-M WW is poised to improve the OEM’s internal supply chain management and meet customer demand for source tagging of IT assets.  The Sentry-M WW can accomplish this regardless of the country in which the equipment is manufactured, distributed or sold.  Further, as corporate operations are merged or expanded, the equipment and other assets therein must be reallocated and transferred to different facilities, even different countries.   As for the end users, they also have stringent demands.  They seek an automated and reliable solution to authenticate and track their equipment for repair, warranty and data collection.  Used internally to reduce supply chain costs or as a feature benefit for end customers, the Sentry-M WW is currently the only tag of its kind that functions across the frequency bands of countries around the world.

What is an RFID tag?

RFID tags are tiny microchips, almost invisible to the naked eye, attached to a printed or plated antenna that is embedded in a card or other object. These devices listen for a radio query. When they sense one, they transmit a response. Many RFID tags are passive, meaning that they use the power from the querying radio signal to transmit their responses. Active tags have batteries, and can transmit a more powerful, longer range response. Each RFID tag has a unique identifier, usually a 64-bit to 128 bit number that can have thousands of trillions of possible values.

Who uses RFID tags?

RFID tags are used in a wide range of applications in industry, government, defense and healthcare. They are used to track and monitor inventory, monitor and locate valuable assets, provide secure identity cards or fobs for premisis access, to track disaster victims in an evacuations and for easy and secure contactless payment systems. The greatest advantage of RFID is that it greatly speeds the acquisition and processing of information, since line of site and close physical interaction between the tag and the reader is not necessary, as it is with bar codes and other identification technologies. The applications for RFID systems are continually expanding.

How are RFID systems implemented?

There are many ‘system integrators’ who have packages that provide tags, RFID readers and the software that collects and manages the information gathered by the RFID network. The system integrator provides a ‘soup to nuts’ implementation service for the customer. These systems can be cost effective for standard track and trace applications. Other firms prefer a more customized approach, because their business process does not fit a system integrator’s cookbook, or because they believe they can build a competitive advantage by designing and building the system themselves. That is, the RFID system becomes part of their ‘secret sauce’. In this approach, elements of the system will be customized to the unique requirements of the implementer. In these cases it is highly advantageous for the firm to engage with RFID specialists, who can ensure that the ‘physical layer’ of the system works as it should, i.e. that the readers and tags communicate reliably and consistently. RF engineering is complex, and having experience in deployment is crucial for rapid, successful implementations.

Though your business and process may be unique, RFID technology may help your company. RFID can help you understand in real time where your inventory or assets are, where your employees are, and if those assets and people are secure. If you already monitor this information, RFID can greatly reduce the time spent collecting it, reducing cost and improving accuracy.

RFID asset tags can allow for worldwide tracking as your product travels around the globe, simplifying manufacturing and distribution problems. RFID consultants can create the correct tag for your own company and help improve your business.

Many RFID consulting services can identify and solve RFID problems, while optimizing options just for you. As each business practice and product is unique, so are each business’s needs. Find out what a RFID consultant can do for you.

The Western Hemisphere Travel Initiative strives to improve border security between Mexico, the Caribbean, Canada and the United States. An element of this initiative includes the creation of a Passport/Border card to replace less secure credentials, such as driver’s licenses, which had previously been accepted at border crossing points for travel within North America. The design of this new Passport card included many physical security features, such as a hologram, special inks and printing, opacity marks as well as an RFID inlay. Because of this full feature set, and a durability requirement of ten years, the manufacturing of this card is a very demanding process.

A major provider of secure credentialing systems to governments and enterprises worldwide, partnered with RCD to develop an RFID inlay that met both the RFID performance and the demanding card manufacturing requirements. Over a relatively brief period, an inlay was developed and tested, which passed the requirements. The card went into product in the second quarter of 2008, and RCD delivered over 6 million inlays during the following twelve months.

In early 2009, a decision was made to upgrade the RFID inlay and other security features of the card, and, once again, the provider turned to RCD for its design expertise. A new inlay was developed, tested and qualified, and is now in production for the second generation of US Passport cards.
