Optical Fingerprint Sensor with Arduino

Overview Fingerprint Sensor is an alternative device for security and verification purposes. In modern technology, it is included in high-end smartphones as an alternative unlock against pass codes or pattern swipes. One application of the fingerprint sensor is that of an attendance monitoring system, which is widely used in offices.
