When you receive a letter, first check whether the seal of the envelope has been unsealed, damaged or re-bonded. Check whether the English name and gender on the front of the credit card are consistent with what you filled in on the application form. Sign your name with a familiar pen on the signature strip on the back of the card.
According to the prompt of the issuing bank, complete the "activation card" at the bank outlet or through telephone banking, that is, open the card, and modify the password at the ATM of the issuing bank in time to ensure the security of the account.
If you don't receive the letter within the time specified by the issuing bank, you should consult the issuing bank in time to find out whether the card has been sent, and check the address to avoid the risk of being lost or stolen in the middle.
