What does a credit card mean?

Credit card is a non-cash transaction payment method. Pre-deposit of cash is not encouraged, consumption first and repayment later are implemented, and interest-free repayment period is enjoyed. Cardholders can decide how to repay by installments, but there are minimum repayment requirements. Generally speaking, credit card is a micro-credit payment tool provided by banks to users, which can be overdrawn. Moreover, this kind of overdraft consumption enjoys 20? 56 days interest-free period; As long as the repayment can be made on time, the interest is free. At the same time, even if there is no money on the credit card, you can withdraw cash from the bank, and the longest repayment period is no more than 60 days. Because the credit card has this overdraft function, the credit card at this time actually becomes a loan bank. Tracing back to the source, the earliest credit card was indeed issued to customers by merchants selling goods on credit, which was equivalent to the bookkeeping that the owner of the tobacco hotel at the entrance of the community was willing to owe.
