摘要： An RFID device such as an RFID tag (2) and method comprising: storing a current read key and a current ownership key; receiving, from the RFID reader system (4), a change read key command and an indication that the RFID reader system (4) holds the current ownership key; and in response, replacing the current read key with a new current read key enabling the RFID device (2) to be read by an RFID reader system (4) holding the new current read key. Also, an RFID reader system (4) and method for an RFID reader system (4) to process an RFID device (2), comprising: issuing a take ownership command to an RFID device (2); receiving a new ownership key from the RFID device (2); applying for authorization of the new ownership key; and receiving from the authorization apparatus (6) the new ownership key and an acknowledgement that may be communicated to the tag as evidence of authorization.
