Generally speaking, association can be achieved in two ways:
1. Counter association-the ID card and the debit card of China Bank of online banking are associated with the credit card that needs to be associated at the counter of China Bank;
Second, online association-log in to China Bank official website, log in to online banking, add an account after logging in, and follow the instructions of the bank step by step.
Also remind cardholders who want to associate two bank cards. The debit card and credit card of China Bank with online banking service must belong to the same person, and the identity cards used by those who handle the two cards are of the same generation.
In short, some information between the two cards should be highly consistent. As long as these conditions are met, the supplementary card of China Bank Great Wall Global Link Credit Card can naturally be linked to the debit card account of the corresponding cardholder.
