Generally speaking, banks will introduce many kinds of credit cards to attract customers to open them. There is no upper limit on the number of cards in general banks. As a card issuer, we are glad to see more cards. The more, the better. The number of transactions of multiple natural credit cards will also increase, thus increasing the income of banks.
There are too many cards to manage. First of all, credit cards generally have an annual fee. You need to swipe your card for a certain number of times or a certain amount to avoid the annual fee. If the number of swipes or the amount is not enough, the annual fee will be lost.
