A TV remote control is powered using RFID principles from an electric field generated by the TV and so the RC requires no batteries. The RC changes the ID field of the data packet it transmits based on what button was pushed so that a first button is associated with a first ID, a second button is associated with a second ID, and so on. In this way, only a single RFID tag need be provided in the RC.
