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
Points to note about the Fingerprint Sensor
Please be aware of the following considerations when using the fingerprint sensor. A failure to follow these guidelines might result in damage to the sensor, sensor failure, fingerprint recognition problems or a lower fingerprint recognition success rate.
Do not scratch or poke the sensor with your nails or any hard or sharp objects.
Do not press the sensor strongly.
Do not touch the sensor with a wet finger or any wet objects - keep the sensor surface dry and free from water vapor.
Do not touch the sensor with a soiled or dirty finger as minute foreign particles of dust and dirt may scratch it.
