Precautions for fingerprint recognition
Fingerprint recognition accuracy may decrease due to a number of
reasons. To maximise the recognition accuracy, check the following before
using the device.
•
At the bottom centre of the product' s screen, there is a built-in sensor
that recognises fingerprints. Be careful not to scratch or damage the
fingerprint sensor with metal objects such as coins or keys.
•
If there are foreign substances (sweat, lotion, water, dirt, grease, etc.)
on the fingerprint sensor or on the finger to be put on the sensor,
fingerprint recognition may not work properly. Wipe the sensor and the
finger clean and remove all moisture before putting the finger on the
sensor.
•
If the finger' s surface is rough due to it being scarred or pruney from
water, the sensor may not be able to recognise the fingerprint. In such
a case, register another fingerprint.
•
If you bend your finger or use the fingertip only, your fingerprint may
not be recognised. Make sure that your finger covers the entire surface
of the fingerprint sensor.
•
Scan only one finger for each registration. Scanning more than one
finger may affect fingerprint registration and recognition.
•
The device may generate static electricity if the surrounding air is dry.
If the surrounding air is dry, avoid scanning fingerprints, or touch a
metallic object such as a coin or a key before scanning fingerprints to
remove static electricity.
