Abstract

A fingerprint verification system for a door includes a digital signal processor (DSP) for being attached to a door, a fingerprint information capturing key and a signal receiving port. Whereby in use, the connector of the fingerprint information capturing key is electrically connected with the signal receiving port. A finger of a user is scanned by the fingerprint information capturing unit for capturing fingerprint information of the user. The captured fingerprint information is transmitted to the DSP through the connector and the signal receiving port for being verified against previous stored fingerprint information. The fingerprint verification system can release a lock of the door or open the door only if they match.

Claims

1. A fingerprint verification system for a door comprising a digital signal processor (DSP) for being attached to a door, a fingerprint information capturing key and a signal receiving port, wherein

the fingerprint information capturing key includes a fingerprint information capturing unit formed at a body thereof, and a connector formed at a front end thereof, the fingerprint information capturing unit and the connector are in communication connection;

the signal receiving port for being fixed to the door is electrically connectable with the connector, the signal receiving port and the DSP are in communication connection;

Whereby in use, the connector of the fingerprint information capturing key is electrically connected with the signal receiving port, a finger of a user is scanned by the fingerprint information capturing unit for capturing fingerprint information of the user, the captured fingerprint information is transmitted to the DSP through the connector and the signal receiving port for being verified against previous stored fingerprint information, the fingerprint verification system can release a lock of the door or open the door only if they match.
