the first credit card was issued in the 192s. Several American oil companies came up with an idea, that is, to issue a card that allows customers to buy gasoline with the card and pay later. It was a simple and practical idea, but it didn't catch on for a long time. Another early credit card was the Diners Club card, which was issued by Ralph SchNedel of new york in 195. This card allows club members to eat in 27 restaurants in new york.

at first, these credit cards can only be used in a few places of consumption. But Shi Nedel soon had the idea of extending the validity of the card to retail stores and wholesale businesses. Soon, someone designed a "universal" card that was effective almost anywhere. In 1958, the first bank card-"Banga Merika" of Bank of America was adopted. Nowadays, people are very familiar with credit card symbols, and they have become an international language. Banks all over the world display their acceptable credit cards.

another important invention, that is, the computer makes it possible to widely use credit cards. By the mid-195s, computers were first used in business, which meant that customers' account information could be easily gathered together and stored. Since then, many other inventions have made credit cards safer and easier to use, such as the idea of adding a magnetic stripe to the card, where information such as the customer's identity and ID number can be entered. Now cards like this have been used in various ways, such as cashing bank loans, guaranteeing checks, and of course, shopping with cards as originally planned.
