As previously reported, the store tracks what customers pick up from the shelves using a combination of cameras, sensors dotting the store and weight scales on some shelves. Once the store’s technology notices a customer has picked up an item from the shelf, it adds that item to the customer’s virtual cart in the Amazon Go app and updates Amazon’s internal records accordingly.
Sheldon of IHL also described a fleet of what he described as cameras hanging from the ceiling of the Amazon Go store. Most are positioned to view the floor at an angle, but some are also pointed directly at the floor. He speculated that the placement of the cameras was a “mixture of art and science,” and that a different location might need the cameras arrayed differently.
Kumar, Amazon’s vice president of technology, also said that while the in-store cameras track shopper movements, they do not use facial recognition, according to The Wall Street Journal.
While most of the store’s functions are made seamless through technology, store associates are still available to check for identification when a customer wishes to purchase alcohol from the store or ask questions that the store’s technology is unable to answer.
