The EPC Class Structure (January 04th, 2007)
Toronto, ON, July, 2006 - The EPC Tag Class Structure is often misunderstood. 'Class' is not the same as 'Generation'. Class describes a tags basic functionality for example whether it has memory or a battery. Generation refers to a tag specification's major release or ver-sion number. The full name for what is popularly called EPC Generation 2 is actually EPC Class 1 Generation 2, indicating that the specification refers to the second major release of a specification for a tag with write-once memory.
