Technology dynamic Reuters reported that Beijing January 22, Amazon announced Sunday local time, after more than a year of testing, Amazon Go convenience store cash register no one open to the public on Monday, this may continue to advance It will significantly change the physical retail trials.

Starting Monday morning at 7 AM (US time), the store will be open to all customers who use the Amazon Go smart app and log in to Amazon accounts. Amazon Go is Amazon's first automated retail store that promises "no need to line up, no checkout, no cashier" and aims to reshape the physical shopping experience.

Convenience stores require consumers to scan their mobile phones as they enter, and then use cameras and other sensors to track their shopping paths in the store. The virtual shopping cart is updated when the consumer removes the item from the shelf. The customer's Amazon account will charge a fee when the customer selects and leaves the store. It is understood that the prices of Amazon Go convenience store products are basically the same as other markets.

Most of the technologies that make the Amazon Go store work are shelves.

Dozens of paperback-sized rectangular black devices hung under the ceiling to monitor the store in real time.

These devices use multiple sensor inputs, just like systems that help autopilot cars recognize people and objects in the field of view. (A combination of video cameras and laser arrays that can analyze images.) An engineer familiar with Amazon Go said in an interview that Amazon spent a lot of time early on in making its computer vision algorithms effective in tracking consumers.

Amazon also conducted a "plot", three Amazonian employees wearing Pikachu clothing trying to deceive the store tracking system, Amazon's algorithm for each hairy customer correct settlement.

It took some time for the system to run, so in December 2016, Amazon announced that the Amazon Go store had been opened to employees for further testing.
