Face-to-face confirmation of visitors with employee ID cards that include photos and system management with IC card type ID cards are now basics for entrance and exit management.
However, to prevent clever photo switching of employee ID cards, impersonation entrance with stolen ID cards, and unauthorized accompanying entrance, a double-check system with facial recognition is needed to strengthen identity verification.
With the use of chameleon codes, facial recognition can be done without stopping, resulting in a smooth flow during peak times of arrival and departure.
Furthermore, with the implementation of facial recognition, it is possible to manage entrance and exit records with visual recognition by "who, when, and where" they entered (left), including face images, leading to improved visibility in entrance and exit record management.
