`
`ABSTRACT
`
`A radio frequency identification device comprises an inte-
`grated circuit
`including a receiver, a transmitter, and a
`microprocessor. Thereceiver and transmitter together define
`an active transponder. The integrated circuitis preferably a
`monolithic single die integrated circuit
`including the
`receiver, the transmitter, and the microprocessor. Because
`the device includes an active transponder,
`instead of a
`transponder which relies on magnetic coupling for power,
`the device has a much greater range.
