Amazon is reportedly looking at bringing its cashierless Go shopping experience to larger stores.
The e-commerce giant is testing the system in Seattle, in a larger space laid out like a big store, The Wall Street Journal reported over the weekend, citing unnamed sources.
Amazon Go stores are designed to let you shop without a wallet or having to stand in checkout lines. You scan the Amazon Go app on your phone as you arrive, pick up items while monitored by the store's cameras and you're charged via your Amazon account as you leave.
All of the current stores are small, since the system struggles with the high ceilings and additional products of bigger spaces, according to the Journal. As a result, it may take time for it to roll out to more large locations, one of the paper's sources said.
It's also unclear if Amazon will use the technology for Whole Foods -- the supermarket chain it bought for $13.7 billion in 2017-- but the Journal's sources note that it's a likely application.
