Cashierless checkout technologies today are delivered in two iterations. The first takes the form of a typical mobile self-checkout -- a shopper scans products with a mobile device as they browse the aisles, then pays for the transaction via a mobile app without having to fumble through their wallet for cash. Consumers are warming up to the concept, with 48% of U.S. consumers expressing the belief that scan-and-go technology would make shopping easier, and 43% saying they would rather try scan-and-go than wait in a checkout line, according to data from GPShopper. The more recent iteration of cashierless has been heavily publicized with the openings of the first 10 Amazon Go stores. Most of the major players within this space have combined AI- and computer vision-based technology with in-store sensors.
