How many retailers are using each type of self-checkout?

It is hard to get reliable data on the extent to which retailers are using Self-checkout technologies. The most common type currently in use is Fixed Self-checkouts, followed by Scan and Go systems and then Mobile Scan and Go and Amazon Go style technologies. The Grocery sector, where customer and product volumes, and space utilisation issues make it a particularly appealing proposition, are by far and away the sector most likely to use this technology thus far. However, other types of retailing are also beginning to use SCO, including the Home Improvement sector, some apparel retailers and convenience stores.
