the earliest credit cards appeared at the end of 19th century. In the 198s, the British clothing industry developed the so-called credit card, and the tourism and business sectors also followed this trend. However, at that time, the card could only be used for short-term commercial credit, and the money still had to be paid as needed, and there was no long-term default and no credit line.
