Debit card is the most common bank card, we call it: savings card, which is the most basic card type of every bank. Other cards include social security cards, medical insurance cards, credit cards and enterprise annuity cards. The difference between debit cards and other cards is that the money of debit cards is entirely at the cardholder's own disposal, and you can use it how you want. Others, such as medical insurance cards, can only be paid through designated medical expenses. Exit is not flexible. In addition, the conditions for getting a card are different. Most people can apply for debit cards, while other cards, such as credit cards, must meet certain conditions before they can apply. At the same time, they may not be approved after applying.
