At present, the application form of Bank of Communications credit card is one form and two cards, that is, when filling out the form at the outlet, the salesman will help you apply for a credit card or ask you whether you need to apply for a debit card at the same time. Generally speaking, the salesman will recommend you or help you choose yes for business indicators, so there will be two cards, a credit card and a debit card. If you don't use a debit card, it is recommended to cancel it at the outlet, because a small management fee is charged for the debit card. If you use it in the future, you will probably be deducted. Unless you don't use it all the time, the bank will automatically cancel it for you after two years.
