Fingerprint utility limitations
TOSHIBA does not guarantee that the Fingerprint utility technology will be
completely secure or error-free. TOSHIBA does not guarantee that the Finger-
print utility will accurately screen out unauthorized users at all times. TOSHIBA
is not liable for any failure or damage that might arise out of the use of the finger-
print software or utility.
How to Swipe the Finger
Using the following steps when swiping fingers for fingerprint registration or
authentication will help to minimize authentication failures:
1. Align the first joint of the finger to the center of the sensor. Lightly touch
the sensor and swipe finger levelly towards you.
While lightly touching the sensor, swipe the finger towards you until the
sensor surface becomes visible.
Ensure the center of the fingerprint is on the sensor when swiping the finger.
❑ Avoid swiping with the finger stiff or pressed-on too hard
Fingerprint reading may fail if the center of the fingerprint is
not touching on the sensor, or when finger is swiped while
pressing hard. Make sure that the center of the fingerprint is
touching the sensor before swiping.
❑ Confirm the center of the fingerprint whirl before swiping
The thumb’s fingerprint has a bigger whirl, which is prone to
misalignment and distortions. This will cause difficulty in
registration and a drop in the authentication success rate.
Always confirm the center of the fingerprint whirl so that it is
swiped along the centerline of the sensor.
❑ When fingerprint reading is not successful
There is a possibility of authentication failures if the finger is
swiped too quickly or too slowly. Follow the onscreen
instructions to adjust the speed of the swipe.
