Banking is the dream of many people, but many times the reality is not as glamorous as it seems. Most credit card salesmen in suits and ties can only choose to leave after their contacts and dreams are "squeezed dry". High salary is more like a legend. Moreover, behind the low threshold of more than 10,000 pieces of information, the risk of non-performing loans in the banking industry is accumulating, and nearly double the overdue credit is also challenging the patience of supervision.

A credit card is a credit certificate issued by a commercial bank or a credit card company to eligible consumers. The form of credit card is a card with the name of the issuing bank, expiration date, number and cardholder's name printed on the front. Consumers with credit cards can go to specialized commercial service departments for shopping or spending, and then the bank will settle accounts with merchants and cardholders, and cardholders can overdraw within the prescribed limit.
