Kura Sushi Inc. on Thursday introduced high-tech cameras at its outlets to monitor conveyor-belt food lanes after a spate of incidents in which customers tampered with foods and utensils.
The major sushi chain operator's system uses artificial intelligence to detect suspicious behavior, such as the repeated opening or closing of sushi plate covers, allowing store employees to deal with inappropriate activity.
The cameras are installed at each table and constantly monitor plates as they move around the food lanes.
