- 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.
- 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.
- After the pass has been read, the visitor is asked to provide biometrics.
- The biometrics unit compares the data with the data stored on the card.
- Do the data match? The data is then sent to the access control system. Then the barrier goes up!
