A mobile communication device (102) is equipped with hardware and/or software components (104) to enable the device to output a data in a form of a radio frequency signal (110), emulating outputting of the data by either an active or a passive RFID transponder (204, 206). The data may be a security key or an identifier. Emulation of an active RFID transponder (204) includes facilitating selection of the data and instruction to output by a user. Emulation of a passive RFID transponder (206) includes detecting for proximal presence of a RFID reader (120). Either case, provision of the data to the mobile communication device may include provision of associated signal attribute(s).
