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

ensure that only the registered or enrolled fingerprint or
fingerprints are used for identification.

❖The fingerprint reader compares and analyzes the unique
characteristics in a fingerprint. However, there may be
instances where certain users are unable to register their
fingerprints due to insufficient unique characteristics in their
fingerprints.
❖A warning message will be displayed when recognition is
abnormal or recognition is not successful within a fixed
duration.
