1. As long as it is a credit card of Bank of Communications, no matter which branch the application is filled in, it will eventually be approved and issued by the Credit Card Center of Bank of Communications;

2. If there are multiple Bank of Communications credit cards, the amount may be different. For specific consumption, the total amount of two cards cannot exceed the amount of the card with the highest amount; For example, for two credit cards of Bank of Communications, with a credit line of 1 and a credit line of 1, the total overdraft limit of credit card consumption cannot exceed 30,000, that is, if the credit card with a credit line of 1 000 has already spent 50,000 cards with a credit line of 30,000.

3. In addition, for the Bank of Communications credit card, multiple cards should be repaid separately, which is irrelevant and inconvenient; If one card has been returned to 200 yuan and the other card is owed to 50 yuan, you still think that you have not paid it off, and you should calculate the late payment fee, interest and so on. Moreover, the overdue interest is calculated from the first consumption of the card in the month, and the principal is calculated according to the total amount owed, which is quite uneconomical;
