METHOD AND APPARATUS FOR WIRELESS MANAGEMENT OF ARTICLES
First Claim
1. A method implemented by a master RFID tag, the method comprising:
- transmitting at least one first RFID read signal to a plurality of RFID tags local to the master RFID tag;
receiving a first RFID response signal from each of the plurality of RFID tags in response to the at least one first RFID read signal, each of the first RFID response signals comprising an identifier associated with an article;
storing each of the identifiers; and
responsive to receipt of a second RFID read signal from an RFID reader, transmitting a second RFID response signal, the second RFID response signal comprising data associated with the identifiers.

Abstract
The present invention is directed to method and apparatus for wireless management of articles. The method is implemented by a master RFID tag. The method includes transmitting at least one first RFID read signal to a plurality of RFID tags local to the master RFID tag and receiving a first RFID response signal from each of the plurality of RFID tags in response to the at least one first RFID read signal. Each of the first RFID response signals includes an identifier associated with an article. The method further includes storing each of the identifiers and, responsive to receipt of a second RFID read signal from an RFID reader, transmitting a second RFID response signal. The second RFID response signal includes data associated with the identifiers. Embodiments of the present invention are also directed to a master RFID tag comprising an RFID tag communication unit, a memory unit and an RFID reader communication unit.
