There is no specific limit on the number of credit cards that each user can apply for in the same bank, but it should be noted that multiple credit cards in the same bank share the same credit limit, whichever is higher. For example, there are two credit cards from the same bank. If the credit limit of one card is 20,000 yuan, and 10000 yuan has been spent, and the credit limit of the other card is 10000 yuan, the annual fees of the two cards should be calculated separately.
