Amazon is reportedly testing its cashier-less technology in larger stores

Those stores use cameras and software to detect what items customers pick up and charges them accordingly, allowing them to forgo the entire check-out process.

Amazons existing stores are the size of a small convenience store and are thus much smaller than your typical grocery store, with fewer items and people to keep track of.

That would allow it to compete with chains like CVS and Walmart, and in order to do so, it would need to fix a range of sizes, from the smaller corner store to the larger supermarkets. In October, Walmart announced that it was opening an experimental cashier-less Sams Club outlet in Texas, in which customers would use an app on their phone to scan items, rather than relying on the stores systems to track their purchases.
