Lawrence Ho’s Melco Crown Entertainment is reportedly stepping up its technology game to prevent banned players from re-entering its casinos.

The casino operator is the first in Asia’s gaming hub to install a specialized face recognition technology developed by German biometric firm Cognitec. The system, called FaceVAC-VideoScan, is capable of detecting people’s faces in live video streams, which are then compared to databases of banned persons.

If there’s a match between the information collected and the photos in the casino’s system, it will immediately send real-time alerts to the security staff who will deny the detected player entry into the casino.

The company also said its software “also allows to compute demographical information, client behavior, people movement in time and space, and frequent visitiors.”
