What is the EPC Gen 2 standard?
EPC Gen 2 is short-hand for the Electronic Product Code Class-1 Generation-2 UHF RFID Protocol, the specification developed by EPCglobal for the second generation RFID air interface protocol and one example of a passive RFID tag protocol. EPC Gen 2 was developed to establish a standard for RFID tags used in supply chain applications (e.g., tracking inventory). The current ratified standard for Class 1 devices operates in the ultra-high frequency (UHF) range (860–960 MHz), supports operation at long distances (e.g., 25–30 feet), and has minimal support for security (e.g., static passwords to access or kill information on the RFID device). The specification can be found at http://www.epcglobalinc.org. It is important to note that EPCglobal is expected to develop specifications for higher class devices that could incorporate more security. These specifications have not been published at this time. While a number of proposals have been made for security in higher class devices, the proposa
