visitor pass temporary access scan
QR Code Access
Entry or attendance verification using a scannable QR code assigned to a user, visitor, ticket, or temporary access credential.
QR codes work alongside biometrics for visitor management, temporary passes, events, and fast check-in workflows where card-based infrastructure is not available.
Frequently Asked Questions about QR Code Access
Can proxy attendance happen with biometric systems?
Not through normal means — the physical presence of the enrolled person is required. The only theoretical risk is a high-quality spoof attack, blocked by liveness detection.
Are QR codes secure enough for access control?
QR codes alone can be photographed and shared. For higher-security zones, QR + face recognition (two-factor) is recommended.
Can QR codes expire automatically?
Yes. Nialabs visitor QR codes can be set with automatic expiry — valid only for a specific time window, preventing unauthorized reuse.
