Tech giant Amazon is reportedly planning to open more stores utilizing their pioneering technology that allows normal operation without the use of cashiers or check-out lines. This technology has already been implemented in multiple retail stores around the country, including locations in Amazon’s native Seattle, San Francisco, and Chicago.

Cameras are used to detect when a customer has removed an item from a shelf. Linked computers tabulate each customer’s accumulated items and charges them based on the preferred payment information already stored in their specific Amazon account.

This model has proved effective thus far, although it is still seen by many as a novelty. It saves customers time and also presents a potential solution to shoplifting.

It is still unclear whether Amazon will implement the system in Whole Foods stores, a grocery store brand the company purchased last year. Such a change could represent major job loss for individual stores.
