Some card issuers have several cards in a set.

2. The cardholder's multiple credit cards in the same bank are an account and share a credit line. The consumption of card A is 1 1,000 yuan, and the available credit line of card B is correspondingly reduced by 1 1,000 yuan.

There are many types of cards in China Merchants Bank, but if it is a set of cards, there is no need to swipe the card separately to reduce the annual fee. If not, you can apply for cancellation of one of them to avoid annual fees.

3. If you want to run a Minsheng Bank credit card, you can choose a single page (I don't know if there are two pages, but there must be a single page). Minsheng Credit Card will not activate automatic cancellation for 6 months, and no annual fee will be generated. It is the only credit card in China that can be cancelled automatically.
