Identity Heft: RFID Muscles Into Consumer Market

A buzz is growing around RFID as it moves away from proprietary apps and toward a more connected future in cell phones, laptops, and other devices.

PERSONALIZATION AND PAIRING
SkyeTek sees a big market in using RFID for personalization. Brunswick, the exercise equipment manufacturer, plans to use the technology to automate the configuration of stair climbers and treadmills. By embedding tags in health-club member- ship cards, clubs automate members' workout histories and save staff time otherwise wasted in manually setting up the machines.

RFID integrates the physical world with IT services and ultimately with Internet Protocol. RFID readers embedded in office equipment like conference phones or copiers can readily automate departmental billing. Sirit Inc. sold 2500 of its Infinity Micro modules to AirGATE for integration into an RFID-enabled telephone system. A telephony OEM is now putting that system into phones in correctional facilities nationwide. Prisoners will wear RFID-enabled wristbands to identify who is making a prison-based collect phone call.

Other RFID developers are licensing their technology, too. In the active RFID arena, Savi Technology opened its technology via the ISO 18000-7 active RFID air protocol standard, operating at 433.92 MHz with applications in shipping container security.

"Broad participation in the licensing program is a sign of a maturing market for active RFID and a confirmation that standardization will continue to turbo-charger this marketplace," says Savi CEO Bob Kramer. He notes that the standard helps establish a baseline for the interoperability of RFID-based electronic seals and container security devices.

NFC NEARLY HERE
Pairing is also crucial for the Near Field Communication (NFC) initiative. NFC offers a two-way, short-range communications protocol. NFC-enabled devices can act as either an RFID tag or reader, depending on the application.

NFC was selected in November as a connectivity solution for Wi-Fi-enabled devices. To set up Wi-Fi communications using NFC, two devices only need to be brought close together. NFC handles the pairing, establishing the communications protocols between them.

According to Manuel Albers, director of regional marketing for the Americas, Identification, at NXP Semiconductors, the first Wi-Fi and NFC combo products should hit the market during the second half of this year. For example, Sirit has demonstrated a USB dongle that incorporates NFC to facilitate Wi-Fi setup, a function that many consumers could use some help with right away.

"Wireless routers have a return rate of up to 70%, simply because people are struggling with setting the device up," says Albers. "Cutting down that return rate could pay for integrating NFC, or at least including a USB fob to facilitate the automatic setup."

Standards groups for Wireless USB, Bluetooth, and Ultra-Wideband (UWB) are considering other NFC "pairing" initiatives. "These are all applications NXP didn't even have in mind when we created NFC, in combination with Sony 2002," says Albers.

Microsoft has joined the NFC Forum and is looking to ensure compatibility and support of NFC with drivers in the Microsoft Windows platform. "Microsoft has a lot of good ideas" on how to use NFC, says Albers, adding, "these are all being discussed under NDA (non-disclosure agreements)."

The cell phone remains the key market focus for NFC. "Once you have a significant deployment of NFC-enabled phones," says Albers, "you have a broad infrastructure of inexpensive readers. Simply add NFC on to the mobile phone, and you have an RFID-enabled reader in your hand."

The NFC-enabled phone, he says, complies with RFID standards: for contactless smart-card payment infrastructure, ISO 14443; for object identification and object tracking, ISO 15693 (for the technical side of the implementation) and ISO 18000 (for the application side of the supply chain). An initiative is under way to harmonize the EPC Gen 2 standard with ISO 18000 for UHF (Gen 2) and HF 13.56 frequencies (Fig. 2).

"With that, you are compliant with already deployed standards, and you can integrate transport and payment and can read tags attached to objects and goods in the supply chain," says Albers. With NFC cell phones integrated into the equation, he adds, "you have very inexpensive readers available." Users can add NFC functionality to existing phones via a Secure Digital (SD) card slot, enabling smart phones like Palm devices with the contactless interface.

RFID ON THE PHONE
IDTechEx expects RFID-enhanced phones to grow to 300 million units by 2010 and 600 million units by 2015 (Fig. 3). LG's Active Tagging Group in Korea says it aims to sell 1 billion active tags by 2010.

IDTechEx also predicts growth from RFID used in combination with other wireless technologies. RFID can be merged with GPS or GSM for identifying and locating people or assets. RFID tags can piggyback on preexisting Bluetooth, Wi-Fi, or two-way radio communications. Examples include Radianse combining active RFID with Bluetooth to locate nurses in hospitals and Connexion2's use of GSM to contact police if social workers are threatened.
