Correct face registration and authentication method
Recommendation for registering a face
When registering a face, maintain a distance of 40cm to 80cm between the device and the
face.
Be careful not to change your facial expression. (Smiling face, drawn face, wink, etc.)
If you do not follow the instructions on the screen, the face registration may take longer or
may fail.
Be careful not to cover the eyes or eyebrows.
Do not wear hats, masks, sunglasses, or eyeglasses.
Be careful not to display two faces on the screen. Register one person at a time.
It is recommended for a user wearing glasses to register both faces with and without glasses.
Recommendation for authenticating a face
Ensure that the face appears inside the guideline displayed on the screen of the device.
If the glasses have been changed, authentication may fail. If the face without glasses has
been registered, authenticate the face without glasses further. If the face with glasses has
been registered, authenticate the face with the previously worn glasses.
If a part of the face is covered with a hat, a mask, an eye patch, or sunglasses, authentication
may fail. Do not cover the face, allow the device to recognize both the eyebrows and the
face.

Finger Placement
Recommended fingers: Index, middle, or ring fingers.
Avoid using the thumb or pinky, as they are difficult to accurately tap onto the fingerprint reader.
Note:
Please use the correct method when pressing your fingers onto the fingerprint reader for
registration and identification.
