Abstract
An object matching method, system and apparatus. The system can include a multiplicity of RFID tags storing corresponding tag data coupled individually to respective objects. Selected ones of the RFID tags can be programmed with tag data associating the selected ones of the RFID tags with one another. At least one RFID reader/interrogator can be configured to interrogate the RFID tags and responsive to the interrogation to read the corresponding tag data. Finally, matching logic can be programmed to determine whether interrogated ones of the RFID tags contain tag data indicating an association between coupled ones of the objects. Notably, the matching logic can be disposed in the RFID reader/interrogator.
