Observe the following before you swipe your finger on the reader,
whether for fingerprint enrollment/registration or recognition.
❖ Wash and dry your hands thoroughly.
❖ Remove static electricity from your fingers by touching any
metal surface. Static electricity is a common cause of reader
failures, especially during dry seasons such as winter.
❖ Clean the reader with a lint-free cloth. Do not use detergent to
clean the reader.
❖ Avoid the following finger conditions for enrollment or
recognition as they may result in fingerprint enrollment errors
or a drop in the fingerprint recognition success rate.
❖ Soaked or swollen finger (e.g., after taking bath)
❖ Injured finger
❖ Wet finger
❖ Soiled or oily finger
❖ Extremely dry skin condition on finger
Observe the following to improve the fingerprint recognition
success rate.
❖ Enroll two or more fingers.
❖ Enroll additional fingers if recognition failure occurs often
using enrolled fingers.
❖ Check your finger condition. Changed conditions, such as
injured, rough, extremely dry, wet, soiled, dirty, oily, soaked or
swollen fingers, may lower the recognition success rate. Also if
the fingerprint is worn down or the finger becomes thinner or
fatter, the recognition success rate may be lowered.
❖ The fingerprint for each finger is different and unique. Please
ensure that only the registered or enrolled fingerprint or
fingerprints are used for identification.
❖ Check sliding position (see illustration below).
