A user input module that enables user input without the relatively high costs associated with dedicated user input mechanisms or the relatively high costs associated with handheld devices. A user input module for a device according to the present teachings includes a set of RFID tags for storing a user input and a switching mechanism for activating the RFID tags such that the RFID tags when activated transmit the user input. Devices may use RFID readers to obtain the transmitted user input and then act on the user input as appropriate.
