DÉTECTION DE CONNECTION D'ÉTIQUETTE-À-ÉTIQUETTE (RFID), MÉTHODES ASSOCIÉES, CIRCUITS ET SYSTÈMES

摘要

Methods, circuits, and systems are disclosed for automatically detecting connections between RFID tags. In one embodiment, a method is provided that includes periodically placing a charge on a node shared between a first RFID tag and a second RFID tag. The method also comprises sensing a voltage at the node at a time subsequent to the placing of the charge. The method also comprises automatically determining whether a connection exists between the first RFID tag and the second RFID tag based on the sensing of the voltage at the node. The first RFID tag and/or the second RFID tag may include circuitry configured to perform the method.
