Precautions for fingerprint recognition
Fingerprint recognition accuracy may decrease due to a number of
reasons. To maximize the recognition accuracy, check the following before
using the device.
• Ensure that the fingerprint sensor is not damaged by a metallic object,
such as coin or key.
• When water, dust or other foreign substance is on the fingerprint
sensor or your finger, the fingerprint registration or recognition may
not work. Clean and dry your finger before having the fingerprint
recognized.
• A fingerprint may not be recognized properly if the surface of your
finger has a scar or is not smooth due to being soaked in water.
• If you bend your finger or use the fingertip only, your fingerprint may
not be recognized. 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 coin or key before scanning fingerprints to
remove static electricity.
