This is the account type of the credit card. Generally speaking, the so-called default credit account refers to the consumer account. When the default account balance is insufficient, it will automatically pay and transfer money, mainly for the convenience of consumption and withdrawal. The so-called "credit" here refers to the lending behavior of financial institutions such as banks that allow users to overdraw their consumption within a specified amount, usually referring to credit cards issued by banks.

The origin of credit card (credit card):

The earliest credit card appeared at the end of 19. From 65438 to 1980s, the so-called credit card was developed in British clothing industry, followed by tourism and business departments. However, at that time, the card could only be used for short-term commercial credit, and the money had to be paid back as needed. There was no long-term default and no credit line.

For credit cards, banks that issue credit cards allow users to overdraw, and as long as they repay on time, there is also an interest-free period. Compared with credit cards, debit cards, that is, savings cards, are not allowed to be overdrawn, and you must save money before you can spend it, but banks generally give some interest to attract users to deposit.
