First Claim
1. A wireless identification device comprising:
- a housing;
circuitry in the housing configured to provide a signal to identify the device in response to an interrogation signal; and
a selectively actuated switch supported by the housing and controlling whether the signal is provided to identify the device, the circuitry including digital circuitry having a digital flag which is toggled between a first state and a second state in response to the switch being pressed, and wherein the circuitry polls the flag and provides the signal to identify the device depending on the state of the flag.
