The biometric sensor reads the biometric data of a holder. The operating/processing module stores a random-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 random-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 random-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. ## Claims ### Claim 1 A card-type biometric identification device for identifying whether or not a to-be-identified holder beside a host system is an authorized holder, the host system stores personal data of the authorized holder and a random-code generating program corresponding to the personal data, the card-type biometric identification device comprising: a biometric sensor for reading and outputting authorized biometric data of the authorized holder and to-be-identified biometric data of the to-be-identified holder;
