Amazon Go store opens in San Francisco's Financial District

Amazon's new store with no cashiers opened Tuesday in San Francisco's Financial District. 

The Amazon Go store is located at California and Battery. 

Using the store's app, customers can walk in, pick up what they want and walkout. Sensors and cameras keep tabs of what you take and automatically charge your Amazon account. Plans for a second San Francisco store are already in the works. On Amazon's website, it says a new store will open this winter on Post and Kearny.
