Patent ID: 7762471

Claim:
An identification token comprising: a body; a radio frequency identification (RFID) integrated circuit (IC) embedded in the body, the RFID IC including a first terminal and a second terminal; an antenna embedded in the body and coupled between said first and second terminals of the RFID IC to form two connections between the RFID IC and the antenna; and a user-actuatable switch supported by the body and coupled to at least one of the terminals of the RFID IC, the switch having a first state and a second state different from the first state; wherein the two connections between the RFID IC and the antenna are uninterrupted such that the antenna is electrically conductively connected to the RFID IC by both connections when the switch is in said first state and are uninterrupted such that the antenna is electrically conductively connected to the RFID IC by both connections when the switch is in said second state; wherein said switch is not coupled to the RFID IC by any terminal other than said first and second terminals; and wherein the RFID IC detects actuation of the switch and responds to said actuation by selecting between two different payment card account numbers stored in the RFID IC; whereby said actuation functions as an input signal to the RFID IC.
