Radio frequency identification system and method
First Claim
1. A radio frequency identification system, comprising:
- a radio frequency identification tag having an Identification code and a set of verifiable data stored therein; and
a radio frequency identification reader which sends a reading request to the radio frequency identification tag, requesting to read a first portion of the set of verifiable data, wherein the radio frequency identification tag further comprising control means, which, when the radio frequency identification tag receives the reading request from the radio frequency identification reader, in case of that the set of verifiable data has not been performed a locking operation, performs the locking operation on the set of verifiable data, so that from then on any data of a second portion of the set of verifiable data cannot be read.
