The face cannot be recognized by the device in verification.
Solutions:
1)
Check if your facial expression, standing posture and distance during
verification are the same with that in enrollment.
2)
Check if the device is under direct sunlight or near the windows.
Verification fails as user wears glasses during verification but not in face
enrollment.
Solution: You can enroll your face wearing glasses in the first or second time of
face capturing, since the device supports 3 times of capturing face templates.
The device makes a misjudgment in verification.
Solution: There is a certain probability of misjudgment. You can re-enroll your
face.
