Long checkout lines frustrate customers and hurt sales. Fortunately, new infrared technology will help manage cashier lanes for better in-store performance.

Irisys’ queue management system uses infrared sensors to monitor in-store customer numbers, average wait time, average line length, and overall store checkout performance.

If checkout performance slips below a minimum service level, the system sends management an alert. Sent to computer or PDA, the alert gives 15 and 30-minute advanced notices on how many lanes will be needed to meet customer demand.

The system has been installed in ten retailers across the U.S., Europe, and Asia. In the U.S., Price Chopper and Kroger are in trial, and global retailer Tesco, has already installed it in more than 800 stores in the U.K. and Ireland.

Technology is by no means a cure-all, but infrared technology may help retailers manage one of the most tedious aspects of the shopping experience.

Retailers need to consider: What’s the most aggravating part of your store’s shopping experience, and in what ways can it be improved?
