Abstract: A portable RFID device includes an analog modulation radio frequency transmitter and a data storage holding audio data files. In response to user entered commands the device retrieves the audio data files, applies digital to analog conversion to generate analog audio signals, and transmits the analog audio signals through the analog modulation RF amplifier. Optionally, the analog modulation RF amplifier is a frequency modulation (FM) modulator and transmitter, optionally using a UHF broadcast FM band. The transmitted analog modulated RF signal is received and played by a receiver and playback device proximal to the transmitter. Optionally, a locking operation is applied after storing the multimedia files, preventing subsequent altering of the files.
