1. The card verification date refers to the date when your card is approved, and the bill date of your card is indicated on the card letter you received.
The bill date means that the issuing bank will regularly summarize and settle all transactions and expenses in your credit card account in the current period every month, calculate the total amount owed and the minimum repayment amount in the current period, and send a statement for you. This date is the billing statement of your credit card.
2. Credit card identification
The credit card has at least the following information on its face:
Front: the name and logo of the issuer, credit card type (organization logo) and holographic anti-counterfeiting mark, card number, English or pinyin name, activation date (generally calculated to the month) and expiration date (generally calculated to the month). The chip account and card magnetic stripe account are relatively independent.
back: the magnetic stripe of the card, the cardholder's signature column (which must be signed after activation), the service hotline, the last four digits of the card number or all the card numbers (to prevent fraudulent use), and the credit card security code (the three digits immediately after the last four digits on the signature column on the back of the credit card are used for credit card activation, password management, TV, telephone and online transactions, etc.).
merchants and banks confirm that the credit card is valid, and contact the bank according to the contract signed with the issuing bank to request authorization. Authorization is to further prove the identity of the cardholder and the amount that can be used. Authorization is generally carried out when the use amount stipulated in the contract is exceeded.
after receiving the authorization notice, the card-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.
