DOUBLE-FINGER, SINGLE-FINGER AND ROLLING FINGERPRINTS ACQUISITION, REGISTRATION AND IDENTIFICATION DEVICE

摘要

Disclosed is a double-finger, single-finger and rolling fingerprints acquisition, registration and identification device, comprising a fingerprint acquirer, a backlight unit, an indication unit and a housing; the fingerprint acquirer is an optical double-finger fingerprint acquirer comprising an optical fingerprint image acquisition unit; the optical fingerprint image acquisition unit comprises an optical system and a circuit control module with a storage unit chip; and the storage unit chip is used to store a functional file so as to complete the registration and identification after the acquisition. The present invention adopts a modularization design to enhance the management and improve reliability, has the characteristics of miniaturized optical system, circuit control module and housing, and overcomes the defect of large size of existing same type double-finger fingerprint acquisition devices, thus further saving cost and improving portability. Used together with a computer, the present invention can complete the functions of user double-finger fingerprints acquisition, double-finger fingerprints comparison, abnormality alarm, control signal output and the like, thus effectively increasing the fingerprint acquisition rate and identification precision.
