My fingerprint has been enrolled but I often get failure in identification.

Answer

Reason 1: The fingerprint was not captured properly.

Solution: Enroll staff fingerprints again. Please put the finger flatly and centrally when enrolling the fingerprint.

Reason 2: Sensor is directly faced with the sun light, which leads to low quality of fingerprint image capture.

Solution: Avoid direct sun light on the sensor.

Reason 3: The fingerprint quality of staff is not so good, with peeling and callus.

Solution: Enroll fingers with comparatively better quality.

Reason 4: Staff does not place the finger properly when clocking.

Solution: Please put the finger flatly and centrally when clocking.

Reason 5: The surface of the sensor is not clean enough.

Solution: Clean the sensor. (Recommended method: Use one-sided adhesive tape to stick on the sensor and then remove the tape.)

Reason 6: Sensor problem. Not good in fingerprint capture.

Solution: Replace the fingerprint sensor
