[单项选择]Most Americans have at least one credit card. They give their owners automatic credit in stores, restaurants, and hotels, at home, across the country, and even abroad. And they also make many banking services available. For many of us the "cashless society’.’ is already here.
While computers offer these conveniences to consumers, they have many advantages for sellers too. Electronic cash registers can do much more than simply ring up sales. They can keep a wide range of records, including who sold what, when, and to whom. This information allows businessmen to keep track of their list of goods by showing which items are being sold and how fast they are moving. Decisions to reorder or return goods to suppliers can then be made.
At the same time these computers record which hours are busiest and which employees are the most efficient, allowing personnel and staffing assignments to be made accordingly. And they also identify preferred customers for promotional campaigns. Compute
A. when the goods were sold
B. the exact salesmen who sold the goods
C. what goods were sold
D. when the goods were returned to the suppliers
