Abstract (en)
[origin: WO0064093A1] A wireless communication system includes a multi-functional portable device and more than one host systems so as to accomplish various functions. The portable device performs at least one specific function with a host system and the host system has a transceiver and a host apparatus. Specifically, in order to achieve the purposes, the portable device includes a storage unit for storing at least a portion of information required in performing the specific function and a transceiver unit for transmitting the information to the host system in a form of an encrypted signal. The transceiver includes a control unit for decrypting the encrypted signal to reconstruct the information and a data interfacing unit for providing the reconstructed information to the host apparatus.
