It was not banks that first issued cards, but some department stores, catering companies, entertainment companies and gasoline companies. In the United States, in order to attract customers, sell goods and expand turnover, some shops and grocery stores selectively provide customers with a credit chip similar to a metal badge, which later evolved into a plastic card as proof of customers' purchase and consumption, and introduced credit services for purchasing goods in businesses, companies or gas stations with credit chips. Customers can buy goods on credit in these credit chip stores and their semicolons and pay according to the contract. The prototype of a credit card is like this.

Almost every young employee has a credit card, and some even have several. Although the late payment fee for credit cards has been cancelled, there are still liquidated damages.

Combined with the overdraft interest rate charged, the upper limit of overdraft interest rate is five ten thousandths of the daily interest rate, and the lowest overdraft interest rate is five ten thousandths of the daily interest rate, up 30%.
