That is, in this embodiment of the application, through set up fingerprint identification chip 20 at the first side of base plate 10, set up light-emitting device 30 and controlling means 50 at the second side of base plate 10 to make leaded light 40 pass base plate 10, make only need one base plate 10 alright set up fingerprint identification chip 20, light-emitting device 30 and controlling means 50, can reduce the thickness of fingerprint identification module, make the fingerprint identification module easily installed.
The embodiment of the application provides a fingerprint identification system, and this fingerprint identification system includes mainboard, tool to lock and the fingerprint identification module in any embodiment among the above-mentioned embodiments. The mainboard is connected with the tool to lock electricity, and the mainboard is connected with the base plate 10 electricity in the fingerprint identification module.
Because the mainboard is connected with the base plate 10 electricity in the fingerprint identification module, sets up fingerprint identification chip 20 on the base plate 10, consequently, acquires fingerprint information at fingerprint identification chip 20, and fingerprint identification chip 20 can match the fingerprint information who acquires with the fingerprint information who prestores, if the fingerprint information who acquires matches with the fingerprint information who prestores, fingerprint identification chip 20 alright in order to send signals to the mainboard through base plate 10. Because the mainboard is connected with the tool to lock electricity, consequently, after the signal that fingerprint identification chip 20 sent is received at the mainboard, the mainboard alright be opened with control tool to lock.
