For the past year, Amazon employees have been test driving Amazon Go, an experimental convenience store in downtown Seattle. The idea is to let consumers walk in, pick up items and then pay for them without ever standing in line at a cashier. Amazon is vague on the mechanics, but the store relies on a mobile app and some of the same sensing technology that powers self-driving cars to figure out who is buying what.
Employees have tried to fool the technology. One day, three enterprising Amazonians donned bright yellow Pikachu costumes and cruised around grabbing sandwiches, drinks and snacks. The algorithms nailed it, according to a person familiar with the situation, correctly identifying the employees and charging their Amazon accounts, even though they were obscured behind yellow polyester.
