Because all bank cards will generate annual fees, generally, if the number of bank cards is less than 3 to 5, money will be deducted. In order to avoid the deduction of fees, the bank cards in normal use should be kept above 3 as much as possible.

The annual fee of bank card usually refers to the annual fee of debit card, but it broadly includes the annual fee of credit card and online banking. Debit cards are partially charged with annual fees, and some banks are exempt from annual fees. The annual fee of credit card is generally charged, and the fee is high, ranging from several hundred.
