1. The registered biometric information is stored on the personal access card that the visitor carries. The access card contains a chip that stores this data securely.
2. At the gate there is a card reader and facial recognition camera, fingervein unit or fingerprint recognition unit. When the visitor wants to gain access, the visitor places the access pass in the card reader.
3. After the pass has been read, the visitor is asked to provide biometrics.
4. The biometrics unit compares the data with the data stored on the card.
5. Do the data match? The data is then sent to the access control system. Then the barrier goes up!
