Abstract
A radio-frequency identification (RFID) device, or other type of device that transmits data in response to a broadcast of energy, may have a switch. The switch may allow an operator to signal whether the device will transmit data when energized. The switch could also allow an operator to select a particular item of data, or a combination of items of data, to be transmitted. Receiving data reflected from the device may signify an action to be performed, or may signify the fact that some physical action (e.g., pressing, by a human finger) has occurred with respect to the device. Thus, device that transmit data when energized may be used to direct the operation of other devices (e.g., by turning such other devices on or off), to implement tactilely-sensitive displays, or as part of other applications.
