Abstract
Protocols, systems, and methods are disclosed for two or more RFID tags to communicate with each other using direct connections, wherein the two or more RFID tags are configured to mate and directly exchange identification information. A disclosed method includes detecting that a first RFID tag is connected to a second RFID tag. A first message comprising a first tag identification is sent directly from the first RFID tag to the second RFID tag, and the first RFID tag receives a first acknowledgement from the second RFID tag if the first tag identification was correctly received. A second message comprising a second tag identification may be sent directly from the second RFID tag to the first RFID tag and a second acknowledgement may be received from the first RFID tag if the second tag identification was correctly received.
