Correct face registration and authentication method
Cautions 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 the 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.
Cautions for authenticating a face
• Ensure that the face appears inside the guideline displayed on the screen of the device.
• If glasses have been changed, authentication may fail. If the face without glasses has been registered, authenticate the face without
glasses. If only the face with glasses has been registered, authenticate the face with the previously worn glasses again.
• 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.
