Mortgage credit card (debit card) is actually an ordinary credit card (debit card). In the process of handling the mortgage, the staff will recommend the user to handle a credit card (debit card), which is commonly called mortgage credit card (debit card). In fact, the card has nothing to do with the mortgage, just because the user is a mortgage customer of the bank, so when applying for a credit card (debit card), the chances of passing the examination and approval will increase.
If users need a credit card, they can apply for a credit card (debit card) at the same time as applying for a mortgage. If there is no demand for credit cards, they can refuse the recommendation of the staff.
