After receiving the application form and related materials submitted by the applicant, the credit card issuing bank shall review the applicant's credit standing. The contents of the audit mainly include whether the contents of the application form are true, evaluating the credit degree of the applicant, and auditing the relevant information of the personal guarantor. Usually, the bank will review the information and economic situation of the applicant according to the application materials to judge whether to issue a credit card to the applicant. The factors considered include the applicant's past credit record, the applicant's known assets, professional characteristics, etc. The specific factors and process of the issuer's audit are trade secrets, which are generally 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.
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. After receiving the authorization notice, the issuing bank will issue an authorization instruction according to the balance of the cardholder's deposit account and the agreement that the bank allows overdraft, and reply whether to agree to the transaction.
