1. A switchable RFID device comprising:
- a first logic input configured for determining a state of a first switch;
a power input configured to receive power wirelessly, the received power being sufficient for powering the integrated and for transmitting a data output signal via the radio frequency antenna; and
a data output configured for generating the data output signal, contents of the data output signal being responsive to the state of the first switch as determined by the first logic input.
