UHF Air Interface Protocol Standard "Gen2v2" (Generation 2 / Version 2)
GS1's EPC "Gen2" air interface protocol, first published by EPCglobal in 2004, defines the physical and logical requirements for an RFID system of interrogators and passive tags, operating in the 860 MHz - 960 MHz UHF range. Over the past decade, EPC Gen2 has established itself as the standard for UHF implementations across multiple sectors, and is at the heart of more and more RFID implementations.
The all new Gen2v2 represents the latest release of GS1's EPCglobal air interface protocol, which has been enhanced in response to the requirements of the EPCglobal user community. Gen2v2 features a number of backwards-compatible, optional features including:
- Untraceable function to hide portions of data, restrict access privileges and reduce a tag's read range.
- Support for cryptographic authentication of tags and readers to verify identity and provenance, as well as reduce the risk of counterfeiting and unauthorized access.
- Enhanced User Memory for "Alteration EAS" and supplementary encodings (such as maintenance logging) during a product's life cycle.
- "Nonremovable" flag for embedded tagging of electronics and sewn-in tagging of apparel, to indicate that a tag cannot easily be removed without compromising the tagged product's intended functionality.
NOTE - tag Recommissioning (introduced in v1.2.0) has been deprecated as of Gen2v2.
