Credit card consumption is a non-cash transaction payment method. Credit cards are divided into credit cards and quasi-credit cards. Credit card refers to a credit card in which the cardholder has a certain credit limit and can spend first and then repay. Quasi-credit card means that the cardholder deposits a certain amount of reserve fund according to the regulations. A credit card is a card with the issuer's name, expiration date, number and cardholder's name printed on the front, and a magnetic stripe and signature strip on the back. 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 limits.
On the card face of a credit card, there are at least the following information: front: name and logo of the issuing bank, credit card type (organization logo) and holographic anti-counterfeiting logo, card number, English or pinyin name, activation date (generally calculated to month) and validity period (generally calculated to month). Chip account and card magnetic stripe account are two relatively independent accounts. Back: the magnetic stripe of the card, the cardholder's signature column (which must be signed after activation), the service hotline, the four or all digits after the card number (to prevent fraudulent use), and the credit card security code (the three digits immediately after the signature column on the back of the credit card are used for credit card activation, password management, TV, telephone and online transactions, etc. ). The merchant and the bank confirm that the credit card is valid and contact the bank for authorization according to the contract signed with the issuing bank. Authorization is the amount that can be used to further prove the identity of the cardholder. Authorization is generally carried out when the usage specified in the contract is exceeded. However, it should be noted that the specific factors and processes of credit card issuer audit are trade secrets, which are difficult for the outside world to understand. Different card-issuing banks have different standards. Therefore, the same materials may have different credit lines and different types of credit cards in different banks, and even some banks will pass the examination and some banks will refuse to issue them.
