Discount giant Home Bargains have introduced a new traffic-light system to help control the number of shoppers in its branch in Yate.

Previously staff members stood outside the store to limit the number of customers at any one time.

Home bargains have now introduced a new light sensor-control system that is placed at the entrance and exit points of the store to monitor how many people are in the shop.

Customers will be allowed to enter Home Bargains stores when the lights turn green.

In addition to people counting, the sophisticated sensor will also be able to track a customer’s journey around a store by 'directly detecting human shape and movement, identifying where they stopped and who they passed by'.

However, the technology will monitor shoppers 'without privacy invasion, as unlike CCTV cameras, the sensor does not collect personal information'.
