Amazon's cashier-free store relies on an RFID-enabled inventory management system

Amazon Go, a store devoid of cashiers and check out lines, opened its first beta store in Seattle. While Amazon has not offered a full technological tour of the facility, a patent filing earlier this year shows the company is using RFID chips to automatically track the exit of materials from a shelf and sync to a handheld device, GeekWire reports. The technology involved allows shoppers to activate an app, select preferred items, then pass through a scanner area that reads purchases, tallies the amount spent,  and ultimately sends the bill directly to the shopper's Amazon card.
