1. Card issuing

After the applicant successfully applies for a credit card, the issuing bank will open a separate credit card account for the cardholder at the issuing bank for shopping, consumption and settlement after cash withdrawal.

Open the card

Because the credit card application is approved by post, there is no guarantee that the recipient is the applicant. In order to protect applicants and banks from being stolen, credit cards have card opening procedures before they are officially opened. Card opening is mainly through telephone or internet. , check the relevant personal information provided at the time of application, and go through the card opening procedures after meeting the requirements. At this time, the applicant becomes the cardholder and can officially start using it after signing on the back of the card. After a credit card is opened, it is generally necessary to set a password for the card.

After accepting a credit card, a credit card merchant or bank shall review the validity of the credit card and the identity of the cardholder.

identify

The credit card has at least the following information on its surface:

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 effective date (generally calculated to month). The chip is attached to the front of the newly issued card, and the chip account and the 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. ).

authorize

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.
