A wireless identification device including 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 circuitry identifies the device. A method of manufacturing a wireless identification device, the method comprising configuring circuitry to provide a signal to identify the device in response to an interrogation signal; coupling the circuitry to a push-on/push-off switch supported by the housing and controlling whether the circuitry provides the signal to identify the device; and encasing the circuitry in a housing such that the switch is actuable from outside the housing by touching a portion of the housing. |

DETAILED DESCRIPTION The invention provides a wireless identification device including a housing, and circuitry in the housing configured to provide a signal to identify the device in response to an interrogation signal.
A selectively actuated switch is supported by the housing and permits operation of the circuitry only while the switch is actuated.
In one aspect of the invention, the switch is a momentary switch.
One aspect of the invention provides a RFID device including a push button switch which, when pushed, allows the RFID device to become active until the switch is pushed again.
The user of the device has control over when the RFID device responds to an interrogator.
In one aspect of the invention, the RFID device includes a wireless receiver, and the switch controls the receiver.
In another aspect of the invention, pushing the switch toggles the receiver between being enabled and disabled.
In one aspect of the invention, the switch is a momentary switch which causes circuitry to latch a signal which enables the device.
When the switch is pressed again the circuitry latches the device into a disabled or inactive mode.
One embodiment of the invention provides a radio frequency identification device comprising an integrated circuit including a receiver, a transmitter, and a microprocessor.
In one embodiment, the integrated circuit is a monolithic single die single metal layer integrated circuit including the receiver, the transmitter, and the microprocessor.
The device of this embodiment includes an active transponder, instead of a transponder which relies on magnetic coupling for power, and therefore has a much greater range.
Another aspect of the invention provides a method of manufacturing a wireless identification device.
Circuitry is configured to provide a signal to identify the device in response to an interrogation signal.
The circuitry is coupled to a push-on/push-off switch supported by a housing.
The switch controls whether the circuitry provides the signal to identify the device
