The earliest institutions that issued credit cards were not banks, but some department stores, restaurants, entertainment industries and gasoline companies. Customers can buy goods on credit in these chip shops and make an appointment to pay.

It is said that one day, Frank McNamara, an American businessman, entertained guests at a restaurant in new york. After eating, he found that he forgot his wallet with him and had to call his wife to bring cash to the restaurant to settle the bill. So McNamara came up with the idea of creating a credit card company. In the spring of 195, McNamara and his good friend Schneider founded DinersClub, which provides members with a card that can prove their identity and ability to pay, and members can charge their expenses with the card. This kind of credit card that does not need to be handled by a bank is still a commercial credit card.

in p>1952, Franklin national bank in California, USA, as a financial institution, first issued a bank credit card.
