Security Scanners & Access Systems

An access control system consists of three core components: credentials (what identifies the user), readers (what captures the credential), and controllers (what decides whether to grant or deny access). These work together to ensure only authorised personnel can enter secured areas.

Credentials include RFID proximity cards, NFC-enabled smartphones, biometric data (fingerprints, facial features), PIN codes, and QR codes. When a credential is presented to a reader, the reader captures the data and sends it to the access controller. The controller checks the credential against its authorisation database and, if valid, sends a signal to release the door lock, turnstile, or gate motor.

Modern cloud-based access control systems store authorisation databases in the cloud, allowing facility managers to add or revoke access credentials from anywhere using a web portal or smartphone app. Real-time access logs record every entry and exit event with timestamps, enabling detailed audit trails and attendance tracking.

Visitor management systems extend this by allowing pre-registration of visitors, generating temporary QR code passes, notifying hosts of visitor arrival, and automatically expiring credentials after the visit period. Integration with fire alarm systems ensures all access points unlock during emergencies.
