The more types you run, the happier the bank will be. Each card needs to be swiped several times to avoid the annual fee. If you have four cards, swipe them 20 times, and if you can't swipe them, you will be charged 4 times the annual fee.

In addition, generally speaking, the credit limit of the credit card of the same bank is the same. For example, if your credit limit is 65,438+0,000, you will reduce the credit limit of three cards with one card. At least, the CCB I run is like this. It's no good for you to do so much. All the benefits are taken up by the bank.
