A: The following situations can resultin a terminal not being able to verify a fingerprint:
(1) Fingerprint was rubbed down;

(3) Serious desquamation of fingers.
If the user’s fingerprint is not able to beverified, please delete it then enroll it again, or use a different finger forenrollment instead. Select the best fingers to enroll (less crinkles, nodesquamation, etc.). When enrolling a user please make sure that thefinger covers the biggest area it can on the sensor. Do a verification testright after enrollment. It is recommended to enroll more than onefingerprint per user.
