Using User Authentication By Fingerprint
■ How to place your finger on the sensor
Pay attention to the following points when performing fingerprint registration or authentication.
• For reliability, align your finger such that the virtual line connecting the white positioning marks on the both
sides of the fingerprint sensor crosses the base of your fingernail, and press your finger to the sensor.
• Make sure your finger covers the finger (detection) sensor. (Do not let your finger float away from the sen-
sor.)
ATTENTION
The following finger conditions may cause a registration or authentication
failure.
• The skin of finger gets rough or is extremely dry.
• The finger surface is wounded or has suffered an abrasion so that the
fingerprint mark becomes thin.
• The fingerprint has been changed due to a rapid gain or loss of weight.
Washing, wiping, or using a different finger may improve the situation.
