How do you pay for things? Do you usually use cash (现金), or do you like to pay by credit card (信用卡)? If you are like a lot of people, you probably have at least one credit card. Also, you might use it more often than you probably should.
Credit cards first became popular in the 1920s, At that time, businesses, such as hotels and companies,
gave credit cards to their best customers (顾客). Unlike today's credit cards, customers could only use these
cards at the Store or business that gave out the card. Customers had to pay for things in full. They couldn't pay
for something a little at a time.
In 1950, a businessman named McNamara started a credit card company - Diners Club. Unlike earlier
credit cards, this card could be used by customers at many restaurants. Customers liked the card because they
didn't have to carry a lot of cash with them. Restaurant owners liked the card, too. Why? They found out that
customers usually spent more money when they could pay by credit card.
In its first year of business, Diners Club issued 200 cards, The customers who got the cards from the
Diners Club could use them at 27 different restaurants. Today, Diners Club has about 8 million customers,
and they can use their cards in over 7. 6 million businesses in more than 200 countries.
