"Standard Market is the latest entry in the emerging fray of retail automation, where companies are throwing cameras, sensors and machine learning into grocery stores to replace the checkout line. In January, Amazon opened its first cashierless Go market in Seattle to the public; it has since opened more of the stores. In China, experiments in cashierless stores abound, using radio frequency identification tags and a self-checkout process that involves scanning a Quick Response code or your face."
"San Francisco got its first completely automated cashierless store, Standard Market. Shoppers who have downloaded the store’s app can go into the 1,900-square-foot space, grab items and simply leave. There is no check-in gate, and there is no checkout swipe. Ceiling cameras identify the shopper and the items, and determine when said items leave with said shopper. Standard Cognition’s approach is different. It relies exclusively on the ceiling cameras and artificial intelligence software to figure out what you are buying. The cameras document shoppers’ movements, speed, stride length and gaze. Once the system decides it has detected potential theft behavior, a store attendant will get a text and walk over for “a polite conversation.”
Visual tracking
Behavioural data: "Cameras document shoppers’ movements, speed, stride length and gaze."
Proof of Concept; results not yet available. However, the journalist reporting on it did accidentally leave the store with an extra item without paying so the technology is not fool proof in its current incarnation.
