One supermarket in Tokyo has managed to solve the problems of shoplifting, mistakes by cashiers, and long lines of customers waiting at cash registers. It is Japan’s advanced computer technology that has come 1 with the answers. Shoppers at an OK supermarket on the outskirts of the city now push a cart 2 a plastic card chained to it and buy from glass cases where the goods are on display. The plastic card has magnetic number imprinted on it.Each customer carries his or her own card, which is collected at the entrance. While shopping, the customer pushes the card into a slot beside 3 items are wanted and pushes a button or two. The glass covered vending machines are connected to a computer that knows the price of every item in the store.Prices of every purchase are added up automatically. When she has finished shopping, the customer hands her card to a cashier who 4 it to the register. A second later the total pops out. Shop lifting is physically impossible.Once you touch a commodity the computer remembers it 5 you hide it or even if you eat it on the spot. A cashier at the OK supermarket is now able to work 15 times faster than his or her 6 at a conventional supermarket. Only two cashiers, for instance, are required at the store, which sells 2,500 separate items.One man is enough to keep the vending machines filled, because if the stock for a certain commodity is 7 to run out, a red lamp in the computer room 8 him or her. 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.
