# Notes on Fingerprint Authentication
<Fingerprint sensor equipped models>

## General notes on fingerprint authentication

- The fingerprint authentication technology does not ensure complete user authentication or complete protection of your data and hardware. Sony assumes no liability for any problems and damages arising out of your use of or inability to use the fingerprint sensor.

- The fingerprint recognition rate depends on your operating conditions and varies among individuals as well.

- In case the built-in storage device has to be initialized, for example after the repair work, the fingerprint templates will be lost. You will have to register them all over again.

- The maintenance and management of data concerning fingerprint authentication must be carried out at your own risk. Sony assumes no liability for any defects arising out of your data maintenance and management.

- A fingerprint sensor may malfunction or be damaged if you scratch its surface with:

- A solid or sharp-pointed object

- Fine objects, for example swiping a finger covered with dirt across the fingerprint sensor

- Discharge static electricity from your finger by touching a metallic object especially during dry seasons (e.g. winter) before scanning your fingerprint. Static electricity may cause the fingerprint sensor to malfunction.

## Notes on registering/authenticating fingerprints

- Fingerprint registration/authentication may fail due to the following hand conditions.
  If you have difficulty registering/authenticating fingerprints, try using different fingers or washing your hands. The clean fingers may improve the fingerprint recognition rate.

- Too dry

- Oily, sweaty, or wet

- Wrinkled after a bath

- Rough or injured (e.g. a cut)

- Dirty

- Thin skin, wrinkled skin, etc.

- The fingerprint recognition rate may be reduced due to fingerprints or dust on the fingerprint sensor. Clean the sensor before registering/authenticating fingerprints.
