Face devices (like ZKTeco SpeedFace) fail in poor lighting or direct sunlight.
: For fingerprint devices, grease or dust on the optical sensor is a primary cause for "Access Denied" messages. Use a soft, lint-free cloth to gently wipe the surface. Optimal Placement
If the failure occurs during "Remote Authentication" or when syncing with software like ZKBioSecurity or ZKBio Time, the issue is likely the data path.
Older ZKTeco optical sensors (green light) have known false-rejection bugs. Download the latest firmware from ZKTeco’s official partner portal and flash via USB. Post-update, re-enroll all users.
If you are staring at a blinking red light or an error message every time you scan your fingerprint or present your face, you are not alone. This error disrupts payroll, delays entry, and compromises security.
ZKTeco systems rely on biometric data, such as fingerprints, facial recognition, or RFID cards, to authenticate users. Despite their widespread adoption and reliability, authentication failures can occur due to:
