Several key manufacturers and technology providers today announced they are submitting a protocol definition designed to provide a much-anticipated worldwide standard for radio frequency identification (RFID) known as EPC UHF Generation 2.

Although RFID technology is going to be required of suppliers to the U.S. Department of Defense and top retailers such as Wal-Mart, the lack of a global standard in the nascent technology has made some suppliers hesitant about investing heavily in RFID. Companies supporting the new protocol include Royal Philips Electronics, Texas Instruments, Impinj, SAMSys Technologies, Q.E.D. Systems, UPM Rafsec and Intermec Technologies.
