Yes, the credit card quota sharing of Shanghai Pudong Development Bank means that although cardholders can apply for multiple credit cards in the same bank, all credit cards in the same bank use a common quota. The reason for sharing the credit card quota of Shanghai Pudong Development Bank is mainly to control risks. For the same person, the bank will give a credit line according to its economic strength. If you exceed this line, you may exceed the economic conditions and be unable to repay. Therefore, banks control risks by sharing credit card quotas to ensure that cardholders' consumption behavior is in line with their repayment ability.
