Identification of credit card
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. ).
