The bank has no limit on the number of credit cards that users can apply for. However, multiple credit card limits of the same bank are shared. If you have three credit cards from the same bank, if the maximum amount is 6000, then the sharing amount of these three credit cards is 6000 yuan, which means the cumulative amount of these three credit cards is 6000 yuan. It should be noted that although the quota is shared, the annual fee should be calculated separately.
