One supermarket in Tokyo has managed to solve the problems of shoplifting, mistakes by cashiers, and long lines of customers waiting at cash registers.

But there are disadvantages too: a customer cannot change his or her mind 9 a purchase. Once 10, the item cannot be put back. The customer must go through a cashier with it first and get a refund later. There are also no fresh vegetables or fish on sale—everything is prepackaged.
