Fingerprint lock-key system and implementation method thereof

Abstract

The invention discloses a fingerprint lock-key system, which comprises a fingerprint identification host machine arranged on an application object and a fingerprint key connected or disconnected with the host machine, wherein the fingerprint identification host machine comprises an interface seat, a power supply, a fingerprint registration press button and a main chip module for identifying and processing fingerprint and storing fingerprint template data; and two connecting points of the power supply equivalent switch of the fingerprint identification host machine are arranged in the interface seat; the fingerprint key is only provided with only one fingerprint sensor and an interface which is matched and connected with the hardware of the interface seat and carries out data transmission; and at least two pins or a lapping contact point which are/is matched with the two connecting points of the power supply equivalent switch in the interface seat are/is arranged in the interface. Under disconnecting state, both the fingerprint identification host machine and the fingerprint key are in open circuits and power down; and under connecting state, the fingerprint identification host machine and the fingerprint key are communicated with the power supply to form a sensing identification return circuit. The fingerprint identification system applying the invention has the advantages of common use, loss prevention, zero power consumption, cost saving and the like, and is beneficial to the rapid promotion and popularization of fingerprint identification technology.
