The present invention relates to a wireless apparatus for identification and multimedia files transmission. To utilize on audio-visual devices, this wireless apparatus integrates an IC card copy protection, a RF (Radio Frequency) wireless communication, and an addressing and communication technologies of communication interface, like USB (Universal Serial Bus) for example, into a designed SOC (System on Chip) to control. In combination with several identification hardware and software, the wireless apparatus installed in audio-visual devices can reduce jamming and illegal copying, and also free from the work of wires pulling.
