7 Proper Fingerprint Enrollment
1) First select finger(s) to enroll
Best Practices suggests enrolling at least one finger from BOTH hands. This
ensures the user can always gain biometric door access, even IF one of their
fingers unexpectedly becomes no longer able to be recognized by the
fingerprint reader (due to cuts, scrapes, dirt, etc. adversely affecting the
fingerprint image quality).
ZKAccess fingerprint readers will give optimal results for fingerprint-matching
if the following recommendations and suggestions are followed:
We recommend enrolling two index fingers (images 3 and 6) or two middle
fingers (images 2 and 7):
Avoid using the thumb, ring or little finger for enrollment. These fingers are
often too difficult to correctly position on the fingerprint sensor and often
result in poorer quality fingerprint reads.
2) Proper Finger Placement
The user’s finger should be placed flat and completely cover the fingerprint
sensor.
Correct Method Good Image Wrong Method Poor Image
The user’s finger should be placed flat (and not turned on its side). The finger
also needs to be placed on the center of sensor.
