Lap scoringPassive and active RFID systems are used in off-road events such as Orienteering, Enduro and Hare and Hounds racing. Riders have a transponder on their person, normally on their arm. When they complete a lap they swipe or touch the receiver which is connected to a computer and log their lap time. The Casimo Group Ltd sells such a system, as does Sweden's SportIdent.
Animal identificationImplantable RFID tags or transponders can be used for animal identification. The transponders are more well-known as passive RFID technology, or simply "Chips" on animals.
Inventory systemsAn advanced automatic identification technology such as the Auto-ID system based on the Radio Frequency Identification (RFID) technology has significant value for inventory systems. Notably, the technology provides an accurate knowledge of the current inventory. In an academic study performed at Wal-Mart, RFID reduced Out-of-Stocks by 30 percent for products selling between 0.1 and 15 units a day. Other benefits of using RFID include the reduction of labor costs, the simplification of business processes, and the reduction of inventory inaccuracies. In 2004, Boeing integrated the use of RFID technology to help reduce maintenance and inventory costs on the Boeing 787 Dreamliner. With the high costs of aircraft parts, RFID technology allowed Boeing to keep track of inventory despite the unique sizes, shapes and environmental concerns. During the first six months after integration, the company was able to save $29,000 in labor alone.
RFID mandatesWal-Mart and the United States Department of Defense have published requirements that their vendors place RFID tags on all shipments to improve supply chain management. Due to the size of these two organizations, their RFID mandates impact thousands of companies worldwide. The deadlines have been extended several times because many vendors face significant difficulties implementing RFID systems. In practice, the successful read rates currently run only 80%, due to radio wave attenuation caused by the products and packaging. In time it is expected that even small companies will be able to place RFID tags on their outbound shipments. Since January 2005, Wal-Mart has required its top 100 suppliers to apply RFID labels to all shipments. To meet this requirement, vendors use RFID printer/encoders to label cases and pallets that require EPC tags for Wal-Mart. These smart labels are produced by embedding RFID inlays inside the label material, and then printing bar code and other visible information on the surface of the label. Another Wal-Mart division, Sam's Club, has also moved in this direction. It sent letters dated Jan. 7, 2008 to its suppliers, stating that by Jan. 31, 2008, every full single-item pallet shipped to its distribution center in DeSoto, Texas, or directly to one of its stores served by that DC, must bear an EPC Gen 2 RFID tag. Suppliers failing to comply will be charged a service fee. The DoD requirements for RFID tags on packages is prescribed in the Defense Federal Acquisition Regulations Supplements (DFARS) 252.211-7006. Positioning of the tag needs to be completed in accordance with the clause and definitions in MIL STD 129 and as of 1 March 2007, EPC Global tags must comply with EPCglobal Class 1 Generation 2 specification. Promotion trackingManufacturers of products sold through retailers promote their products by offering discounts for a limited period on products sold to retailers with the expectation that the retailers will pass on the savings to their customers. However, retailers typically engage in forward buying, purchasing more product during the discount period than they intend to sell during the promotion period. Some retailers engage in a form of arbitrage, reselling discounted product to other retailers, a practice known as diverting. To combat this practice, manufacturers are exploring the use of RFID tags on promoted merchandise so that they can track exactly which product has sold through the supply chain at fully discounted prices. Human implantsImplantable RFID chips designed for animal tagging are now being used in humans. An early experiment with RFID implants was conducted by British professor of cybernetics Kevin Warwick, who implanted a chip in his arm in 1998. In 2004 Conrad Chase offered implanted chips in his night clubs in Barcelona, Spain and in Rotterdam, The Netherlands, to identify their VIP customers, who in turn use it to pay for drinks. In 2004, the Mexican Attorney General's office implanted 18 of its staff members with the Verichip to control access to a secure data room. Security experts have warned against using RFID for authenticating people due to the risk of identity theft. For instance a man-in-the-middle attack would make it possible for an attacker to steal the identity of a person in real-time. Due to the resource constraints of RFIDs it is virtually impossible to protect against such attack models as this would require complex distance-binding protocols. LibrariesAmong the many uses of RFID technology is its deployment in libraries. This technology has slowly begun to replace the traditional barcodes on library items (books, CDs, DVDs, etc.). The RFID tag can contain identifying information, such as a book's title or material type, without having to be pointed to a separate database (but this is rare in North America). The information is read by an RFID reader, which replaces the standard barcode reader commonly found at a library's circulation desk. The RFID tag found on library materials typically measures 50 mm X 50 mm in North America and 50 mm x 75 mm in Europe. It may replace or be added to the barcode, offering a different means of inventory management by the staff and self service by the borrowers. It can also act as a security device, taking the place of the more traditional electromagnetic security strip And not only the books, but also the membership cards could be fitted with an RFID tag. While there is some debate as to when and where RFID in libraries first began, it was first proposed in the late 1990s as a technology that would enhance workflow in the library setting. Singapore was certainly one of the first to introduce RFID in libraries and Rockefeller University in New York may have been the first academic library in the United States to utilize this technology, whereas Farmington Community Library in Michigan may have been the first public institution, both of which began using RFID in 1999. In Europe, the first public library to use RFID was the one in Hoogezand-Sappemeer, the Netherlands, in 2001, where borrowers were given an option. To their surprise, 70% used the RFID option and quickly adapted, including elderly people. Worldwide, in absolute numbers, RFID is used most in the United States (with its 300 million inhabitants), followed by the United Kingdom and Japan. It is estimated that over 30 million library items worldwide now contain RFID tags, including some in the Vatican Library in Rome. RFID has many library applications that can be highly beneficial, particularly for circulation staff. Since RFID tags can be read through an item, there is no need to open a book cover or DVD case to scan an item. This could reduce repetitive-motion injuries. Where the books have a barcode on the outside, there is still the advantage that borrowers can scan an entire pile of books in one go, instead of one at a time. Since RFID tags can also be read while an item is in motion, using RFID readers to check-in returned items while on a conveyor belt reduces staff time. But, as with barcode, this can all be done by the borrowers themselves, meaning they might never again need the assistance of staff. Next to these readers with a fixed location there are also portable ones (for librarians, but in the future possibly also for borrowers, possibly even their own general-purpose readers). With these, inventories could be done on a whole shelf of materials within seconds, without a book ever having to be taken off the shelf. In Umeå, Sweden, RFID is being used to assist visually impaired people in borrowing audiobooks. In Malaysia, Smart Shelves are used to pinpoint the exact location of books in Multimedia University Library, Cyberjaya. In the Netherlands, handheld readers are being introduced for this purpose. The Dutch Union of Public Libraries ('Vereniging van Openbare Bibliotheken') is working on the concept of an interactive 'context library', where borrowers get a reader/headphones-set, which leads them to the desired section of the library (using triangulation methods, rather like GPS) and which they can use to read information from books on the shelves with the desired level of detail (e.g. a section read out loud), coming from the book's tag itself or a database elsewhere, and get tips on alternatives, based on the borrowers' preferences, thus creating a more personalised version of the library. This may also lead them to sections of the library they might not otherwise visit. Borrowers could also use the system to exchange experiences (such as grading books). This is already done by children in the virtual realm at mijnstempel.nl, but the same could be done in physical form. Borrowers might grade the book at the return desk. However, as of 2008 this technology remains too costly for many smaller libraries, and the conversion period has been estimated at 11 months for an average-size library. A 2004 Dutch estimate was that a library which lends 100,000 books per year should plan on a cost of €50,000 (borrow- and return-stations: 12,500 each, detection porches 10,000 each; tags 0.36 each). RFID taking a large burden off staff could also mean that fewer staff will be needed, resulting in some of them getting fired,but that has so far not happened in North America where recent surveys have not returned a single library that cut staff because of adding RFID. In fact, library budgets are being reduced for personnel and increased for infrastructure, making it necessary for libraries to add automation to compensate for the reduced staff size. Also, the tasks that RFID takes over are largely not the primary tasks of librarians. A finding in the Netherlands is that borrowers are pleased with the fact that staff are now more available for answering questions. A concern surrounding RFID in libraries that has received considerable publicity is the issue of privacy. Because RFID tags can -depending on the RFID transmitter & reader- be scanned and read from up to 350 feet or 100 m (eg Smart Label RFID's), and because RFID utilizes an assortment of frequencies (both depending on the type of tag, though), there is some concern over whether sensitive information could be collected from an unwilling source. However, library RFID tags do not contain any patron information, and the tags used in the majority of libraries use a frequency only readable from approximately ten feet. Also, libraries have always had to keep records of who has borrowed what, so in that sense there is nothing new. However, many libraries destroy these records once an item has been returned. RFID would complicate or nullify this respect of readers' privacy. Further, another non-library agency could potentially record the RFID tags of every person leaving the library without the library administrator's knowledge or consent. One simple option is to only let the book transmit a code, that will only mean anything in conjunction with the library's database. Another step further is to give the book a new code every time it is returned. And if in the future readers become ubiquitous (and possibly networked), then stolen books could be traced even outside the library. Removing of the tags could be made difficult if they are so small that they fit invisibly inside a (random) page, possibly put there by the publisher.
Schools and universitiesSchool authorities in the Japanese city of Osaka are now chipping children's clothing, back packs, and student IDs in a primary school. A school in Doncaster, England is piloting a monitoring system designed to keep tabs on pupils by tracking radio chips in their uniforms. St Charles Sixth Form College in West London, England, started September, 2008, is using an RFID card system to check in and out of the main gate, to both track attendance and prevent unauthorized entrance. As is Whitcliffe Mount School in Cleckheaton, England which uses RFID to track pupils and staff in and out of the building via a specially designed cards.In the Philippines , some schools already use RFID in IDs for borrowing books and also gates in that particular schools have RFID ID Scanners. These Schools are Claret School of Quezon City , Colegio de San Juan de Letran and Other private Schools
MuseumsRFID technologies are now also implemented in end-user applications in museums. An example is the custom-designed application "eXsport" at the Exploratorium, a science museum in San Francisco, California. A visitor entering the museum receives an RF Tag that can be carried on a card or necklace. The eXspot system enables the visitor to receive information about the exhibit and take photos to be collected at the giftshop. Later they can visit their personal Web page on which specific information such as visit dates, the visited exhibits and the taken photographs can be viewed
Social retailingWhen customers enter a dressing room, the mirror reflects their image and also images of the apparel item being worn by celebrities on an interactive display. A webcam also projects an image of the consumer wearing the item on the website for everyone to see. This creates an interaction between the consumers inside the store and their social network outside the store. The technology in this system is an RFID interrogator antenna in the dressing room and Electronic Product Code RFID tags on the apparel item. |
