Amazon Just Opened a No-Cash, No-Card, No-Checkout Grocery Store

The future is here, and if Amazon's first brick-and-mortar store is any indication, it's a cashless, queue-less shopper's dream. Today, the online commerce company opened the doors of Amazon Go, a grocery store in Seattle where shoppers browse everyday items, put them in their bags, and exit the store without having to take out their wallets. Yes, really.

Here's how it works: Customers download an app which permits real-time tracking and is linked to their payment details. They swipe their phone upon entry to the store, and when they pick up an item, hundreds of cameras along with "algorithms and sensors" keep track of what they choose, creating a "virtual shopping cart," New York Daily News reports. After exiting the store, shoppers are sent a list of their purchases and charged to their Amazon account.

So what happens if you're wrongly charged? The tech giant says the system is extremely accurate, but if shoppers wish to refute a charge, they can simply hit the "refund" button on the receipt to be credit—no returns necessary. Apparently, the method is built on the honor system, and Amazon believes those looking to take advantage will be in the minority. Here's to a cashless, queue-less future.
