Observe the following to improve the fingerprint recognition success rate.
■
Enroll two or more fingers.
■
Enroll additional fingers if a recognition failure often occurs when using
already enrolled fingers.
■
Check the condition of your finger - any conditions which have changed
since enrollment, such as injury, rough skin, and 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.
■
As the fingerprint for each finger is different and unique you should
ensure that only the registered or enrolled fingerprint or fingerprints are
used for identification.
■
Check the position and speed at which you swipe your finger across the
sensor - please refer to the preceding drawing.
■
The fingerprint sensor 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.
■
The recognition success rate may differ from user to user.
