Abstract

A method for providing identification and access with respect to a passive radio-frequency tag in a tag population, the passive tag receiving ACK commands includes an identification parameter in the form of a 16-bit number. The method includes a step of receiving a command for initiating an inventory round or a command for initiating a tag access, generating a 16-bit value referred to as first or second binding handle, backscattering the first or second binding handle, receiving an ACK command, and analyzing the identification parameter of the ACK command, and in a case where the identification parameter includes the reader identifier then ignoring the ACK command.
