Precautions for using iris recognition
Before using iris recognition, keep the following precautions in mind.
•
To protect your eyes, keep the screen at least 20 cm away from your face when using iris
recognition.
•
If you attach screen protectors (privacy protection films, tempered glass protectors, etc.),
the recognition may fail.
•
Do not use iris recognition with infants. Doing so may damage their eyesight.
•
Anyone who has experienced dizziness, seizures, loss of awareness, blackouts, or other
symptoms linked to an epileptic condition, or has a family history of such symptoms or
conditions, should consult a doctor before using iris recognition.
•
Biometric data collected and stored locally by the iris scanner is not intended for any
diagnostic, therapeutic, or preventative medical purposes.
For better iris recognition
The tablet may not recognise your eyes when:
•
something prevents the camera from getting a good view of your irises (e.g. glasses, low
eyelids, recent eye surgery, disease, dirt, damage to the camera, or excessive movement).
•
the lighting is very different from when you recorded your irises (e.g. direct sunlight).
Hold your device about 25-35 cm away from your face with the screen facing towards you.
