There will be something missing at two Whole Foods stores opening next year: the rows of cashiers.

Amazon, which owns the grocery chain, said Wednesday that it will bring its cashier-less technology to two Whole Foods stores for the first time, letting shoppers grab what they need and leave without having to open their wallets.

Cameras and sensors track what’s taken off shelves.

Items are charged to an Amazon account after customers leave the store with them.

But there will be an option for those who want to shop the old-fashioned way: Self-checkout lanes will be available that take cash, gift cards and other types of payment.

One of the new stores will be in Washington, D.C., the other in Sherman Oaks, California.
