Not pressing hard enough
Lightly dragging thumb over the sensor is not sufficient for the sensor to see the
print. The finger must make solid contact, which requires medium pressure. On
a scale of 1 to 5, with 1 being very light and 5 being hard, pressure should equal
about a 3.
• Starting a swipe too high or too low
With thumb hovering over top the sensor, align the first knuckle with the sensor
as the starting point for swiping. This exposes only the central and most feature-
rich portion of the fingerprint to the sensor during a swipe.
• Swiping too fast or too slow
Use a moderate, steady speed. Swiping too fast or too slow prevents the sensor
from collecting the necessary data for processing.
• Keep thumb level while swiping, do not tilt or rock thumb to the left or right.
Troubleshooting Level 3
Approximately 10% of all users have a fingerprint that is not centrally located. So the
area that is swiped over the sensor is not very feature-rich and results in a low
quality fingerprint template:
• Examine the user’s fingerprint in bright light to determine if its pattern
(typically a bull’s eye, U shape, or S shape) is off-center and closer to the left
or right side of their finger.
• If their print is off-center, coach the user to roll their finger to the left or right
accordingly when swiping such that the main pattern of their fingerprint is fully
exposed to the sensor. They will always have to use the same swiping
technique (during enrollment and day-to-day device use).
Troubleshooting Level 4
If enrollment of the thumbs is still failing or verification is sluggish, try enrolling other
fingers, starting with the primary index finger. If index fingers cannot be enrolled,
attempt to enroll any other finger, with the goal of having any two fingers enrolled,
one as a primary and one as a back-up.
The device is designed for thumbs so that is can be operated with one hand, but any
finger can technically be enrolled.
