LOCK AND SWITCH USING PRESSURE-TYPE FINGERPRINT SENSOR

摘要

A lock has a pressure-based fingerprint sensor, the sensor detects the fingerprint pattern of the finger that presses the sensor, a matching circuit prepares a fingerprint code based on the detected fingerprint pattern, this code is compared with registered fingerprint codes stored in a memory device to determine whether there is a match, and if there is a match, a control unit unlocks the locking mechanism of a concerned object.
