RFID Spec approved

EPCglobal's next-generation standard boosts read rate of RFID tags



EPCglobal Inc. gave a much-anticipated holiday gift last week when it approved the UHF Generation 2 RFID standard. The nonprofit organization chartered to drive standards for radio-frequency identification technology completed feasibility testing of the standard earlier this month.

The specifications are heralded as the first UHF RFID open architecture completely designed by a committee. Supply-chain benefits dependent on Gen 2 are global interoperability, international vendor support, multiple read/write capabilities that could potentially change the economic climate by delivering a quicker return on investment, and data-communication speeds at more than double tags available today.

The projected read rate for Gen 2 tags in the United States under a simulated environment is 1,500 per second, versus roughly 100 tags per second for tags available today. RFID vendors are excited. "The wider the pipe, the more information you can pump through it," says Tony Sabetti, director of retail supply chain at TI-RFid Systems, which is poised to launch new products based on the Gen 2 standard.
