If it is a debit card, I will take my ID card and bank card to the counter to activate it. It has been activated during general processing. If it is a company's salary card, that is, an ordinary savings card, you need to modify the initial password before you can use it. You can change it at the nearest ATM. If it is a credit card, you need to call the bank with the mobile phone number reserved by the bank and set the password to activate according to the prompt.
