Troubleshooting
<If fingerprint authentication takes too long>
1. If the terminal uses 1:N authentication in network mode,
server overload may occur, resulting in slow authentication
and recognition. In this case, a dedicated server should be
used.
2. Check if the finger and the sensor are clean. Clean the finger
and the sensor. If the user’s finger is hurt, the user must
register another fingerprint.
3. If the fingerprint is not clean, lower the security level of the
user and use the 1:1 authentication method.
4. Input the user’s ID in 1:1 mode and check if the user exists.
<If fingerprint is not registered>
If the finger is too dry or humid, fingerprint image quality may be
poor and may not register. Dry or moisturize the finger before
registering the fingerprint.
<If RF card authentication fails>
1. Check your RF card type matches with the RF option of
Terminal.
