Soyal Fingerprint reader with Capacitive Sensor
Capacitive sensor utilize the principles associated with
capacitance in
order to form fingerprint images. Compared to optical
scanner, capacitive sensor can tolerate wider range of
fingerprint condition.
Capacitive technology eliminates the need for clean,
undamaged epidermal skin and a clean sensing surface,
therefore it able to scan sweaty, mild oily and mildly
scratched fingers. However, it still can not tolerate
severely damaged or greased fingerprint.
