Abstract
A card-type biometric identification device includes a biometric sensor, an operating/processing module, a remote transceiver, and a rechargeable battery. The biometric sensor reads the biometric data of a holder. The operating/processing module stores a pseudorandom-code generating program, personal data, and authorized biometric data of the holder, and may then receive and process to-be-identified biometric data. After judging that the to-be-identified biometric data substantially matches with the authorized biometric data, the module generates and outputs a to-be-identified code by the pseudorandom-code generating program. The remote transceiver outputs the personal data to a host system to enable the host system to generate an authorized code by the pseudorandom-code generating program, which is stored in the host system and corresponds to the personal data. Comparing the authorized code with the to-be-identified code may judge whether or not the to-be-identified holder is an authorized holder.
