Avoid swiping with your finger stiff or pressed too hard onto the sensor, and take care to ensure that the center of the fingerprint is touching the sensor before swiping. Either of these conditions may cause fingerprint reading to fail.
Check the center of the fingerprint whorl before swiping and then ensure this is swiped along the center line of the sensor.
There is a possibility of authentication failures if the finger is swiped too quickly or too slowly - follow any
