Basics
For better fingerprint recognition
Prevent the fingerprint recognition sensor from being
•
scratched or damaged by metal objects, such as coins,
keys, and necklaces.
Ensure that the fingerprint recognition sensor and your
•
fingers are clean and dry.
The fingerprint recognition sensor may not recognize
•
fingerprints that are affected by wrinkles or scars.
The fingerprint recognition sensor may not recognize
•
fingerprints from small or thin fingers.
If you bend your finger or use your fingertips, the
•
fingerprint recognition sensor may not recognize your
fingerprints. Make sure to cover the entire fingerprint
recognition sensor with your finger.
To improve recognition performance, register the
•
fingerprints of the hand you use most often to perform
tasks.
In dry environments, static electricity can build up in the
•
computer. Avoid using this feature in dry environments
or before using the feature, discharge static electricity by
touching a metal object.
