Amazon wants to help you shop with just your smartphone.

Right. They've already done that. But in addition to revolutionizing online shopping, the tech giant is making moves in brick and mortar.

On Monday, the tech giant unveiled Amazon Go, its new initiative for in-store shopping. The first store opened in Seattle, Amazon's headquarters and offers breakfast, lunch, dinner and snacks.

At Amazon's stores, customers don't need to wait in line or checkout formally. There are no cashiers. Customers simply use Amazon's new Go app.

The store is powered by what Amazon has dubbed its "Just Walk Out" technology, which includes computer vision, sensor fusion and deep learning.

"We created the world’s most advanced shopping technology so you never have to wait in line. With our Just Walk Out Shopping experience, simply use the Amazon Go app to enter the store, take the products you want, and go! No lines, no checkout," a description of the project reads.

For now, the store is only open to Amazon employees who are participating in a testing program. It is expected to open to all in early 2017.
