Environment
The scanner should avoid direct sun light, high temperature, humid conditions and rain.
When it is dry, the scanner may not recognize your fingerprint successfully. You can blow your
finger and scan again.
Others
If your fingerprint is shallow, or it is hard to scan your fingerprint, we recommend you to use other
authentication methods.
If you have injuries on the scanned finger, the scanner may not recognize. You can change another
finger and try again.
