Technology has come to the marketplace. In many U. S stores the cash【C1】______has been replaced by a computer that quickly and easily calculates the cost of items being bought.
Back in the early 1960s, when the laser【C2】______developed, it was viewed by some as a fascinating research tool; others called it a【C3】______toy. Since that time, the laser has proved to be an【C4】______of many uses. In fact, in many places it’s becoming a part of【C5】______life. Take, for example, what’s happening at some supermarkets. Food-shopping Americans are coming【C6】______with lasers and computers for the first time. But they’re hardly【C7】______it, until they get to the checkout line. With scarcely a glance at the items, the clerk【C8】______them across a hole, where a special marking on each item is scanned by a low-powered laser【C9】______inside the machine, connected to a remote computer. It started a few years ago, when food processors【C10】______the time had come to put code markings on every one of their thousands of food products. This would make them【C11】______identifiable to a computer. The scanning laser beam was an【C12】______device for reading these markings, and so the Universal Product Code was born.
【C13】______every package today, every can and bottle, has these unique symbols.【C14】______is the time-consuming stamping of prices on each item. Prices are shown【C15】______the shelf.
This mew technology promises to【C16】______food products moving smoothly on and off supermarket shelves, which will help keep overhead down and prices【C17】______At the end of each business day, the remotely-located computer gives the store manager a total picture of the day’s【C18】______--what the needs to restock,【C19】______, and what he can mark down and put on sale.
As for the customer, the most dramatic change is【C20】______checkout lines keep moving.
