RADIO FREQUENCY IDENTIFICATION SYSTEM AND METHOD
First Claim
1. A radio frequency identification system, comprising:
- a multi-core tag including a plurality of radio frequency identification tags, each radio frequency identification tag having an identification code and at least one set of verifiable data stored therein; and
a radio frequency identification reader which sends a reading request to more than one radio frequency identification tag in the multi-core tag, requesting to read a first portion of one of the at least one set of verifiable data stored in the radio frequency identification tag, and authenticates the multi-core tag based on the data read from the multi-core tag, whereineach radio frequency identification tag in the multi-core tag further comprises control means, which, when the radio frequency identification tag receives the reading request from the radio frequency identification reader, in the event that all the data of the requested set of verifiable data is readable, performs a first operation so that from then on at least one data of the requested set of verifiable data cannot be read.
