is a global leader in biometric security, producing millions of fingerprint and facial recognition devices for access control and time attendance. However, even the most reliable hardware can encounter a frustrating roadblock: Authentication Failure. Check the Ethernet cable connection or Wi-Fi signal
Lower the threshold slightly (e.g., from 45 to 35 for fingerprints) to make matching more forgiving. Note: Setting this too low increases security risks by allowing false positives. 2. Check Device Power and Voltage Stability However, even the most reliable hardware can encounter
The most common cause of failed biometric recognition is a physical barrier between the user and the sensor.
