The schematic diagram of a kind of sapphire fingerprint machine scanning panel that Fig. 2 provides for the utility model.
Embodiment
Below in conjunction with accompanying drawing, describe detail of the present utility model and job step in detail:
As shown in Figure 1; fingerprint machine system of the present utility model has comprised sapphire fingerprint machine scanning panel 1, fingerprint collecting equipment 2, fingerprint comparison module 3 and information feedback device 4; wherein; sapphire fingerprint machine scanning panel 1 covers on fingerprint collecting equipment 2; outside its Main Function protection scanner inner member is not exposed to; therefore it need have the feature that transmittance is high and wear-resisting, sapphire wafer than it existing employing tempered glass excellence many.Fingerprint collecting equipment 2 can be specifically crystal probe, and fingerprint collecting equipment 2 is connected with fingerprint comparison module 3, and fingerprint comparison module 3 is connected with information feedback device 4.Fingerprint machine of the present utility model is fingerprint machine specifically, can be also palmmprint machine.
