Product origin:

A credit card is generally a special carrier plastic card with a length of 85.60 mm, a width of 53.98 mm, and a thickness of 1 mm. The name of the card issuer, validity period, number, and cardholder are printed on the front. The cardholder's name and other contents are included on the back with a chip, magnetic strip, and signature strip. Cardholders can use their credit cards to shop and spend money with special entities and deposit and withdraw cash from banks.

The earliest credit card appeared at the end of the 19th century. In the 1880s, the British clothing industry developed so-called credit cards, and the tourism and business sectors followed suit. However, the cards at that time could only be used for short-term commercial credit, and the money still had to be paid as and when used. Long-term arrears were not allowed, and there was no credit limit.
