The fingerprint reader illuminates blue when in standby and red when fingerprint authentication is successful.
If it does not emit light red
The reader cannot read the fingerprint information. Authentication takes some getting used to. If you get the hang of it, there are many cases in which it is possible for someone who was not authenticated successfully at first . Please try the following points for reference.
- When placing your finger on the fingerprint reader, place it gently, slightly, and horizontally.
- If the certification surface is noticeably dirty, use a soft cloth to remove it.
- If you have a rough hand or have a thin fingerprint, it is easier to authenticate your non- dominant finger than your dominant hand, and the fingers that you rarely use rather than the ones you often use.
- If authentication fails, re-register your fingerprint to find a finger that is easy to authenticate. (Since the little finger is thin, it is not suitable for fingerprint authentication.)
If you still cannot authenticate
There are some people who cannot easily pass the authentication because of the thin fingerprint pattern or the extremely dry surface .
In this case, we recommend that you also use password authentication.
