This is the best summary I could come up with:
It built a system that uses radio-frequency identification, known as RFID, to track your purchases as you leave the store.
Customers come into the store, pick out what they want, and walk through an “exit gate” that scans the tags and tallies up the bill.
RFID tags are a longtime staple of the people- and thing-tracking industries: they’re a handy way to quickly check inventory in a warehouse, keep your luggage from getting lost, and even get you into Disney World.
It may not feel quite as cool to go through a scanner before you leave as it does to just walk out of the building, but the pitch for Amazon here is that an RFID system will be drastically easier for companies to implement.
Amazon says its Just Walk Out testing has shown huge increases in customer traffic thanks to the shorter lines and many more transactions because the process is so simple.
Amazon itself may be pulling back on physical retail stores, but it’s clearly still invested in real-world shopping logistics problems.
