Abstract
Systems and techniques for control of RFID devices. An RFID device has an antenna connected with a switch or switches whose states can be changed so as to disable or reduce the effective range of the antenna. The RFID device includes a transceiver that uses the antenna to carry on communications with an RFID reader. The transceiver can set the states of switches in order to set the reader to a desired state. The reader is capable of issuing commands to the RFID device, acted on by the transceiver in order to set states of switches in order to achieve a desired state for the RFID device. The reader may issue commands through RF communication, or alternatively may issue commands through a close proximity interface, for example through contacts or through an inductive connection, allowing the state of the device to be reset after the RF capability of the device has been disabled or reduced.
