Self-checkout shopping carts¹are equipped with cameras, sensors, and a scale to automatically detect and log items on a digital display behind the handle. The technology makes it possible for shoppers to leave the store without going through a traditional checkout line.A self-checkout or a self-service checkout²allows a customer to handle the entire checkout process by themselves. While they’re more common in supermarkets, you’re just as likely to encounter them at department and convenience stores. In a traditional checkout, you put your purchases in a cart and stand in line. In a self-checkout, you scan the items yourself and bag them as you go. You then pay for your purchases using a credit card or cash, and you’re done.
