1. Bank card is the collective name for various account cards issued by banks to customers: including debit cards and bank credit cards.

2. Debit cards developed from savings accounts. The account balance in a debit card is the depositor's deposit in the bank. But debit cards can do much more than traditional savings. In addition to deposits, withdrawals, and transfers, debit card accounts can be linked to all personal businesses and accounts at the bank. For example, through a debit card, all current, fixed-term, local currency, and foreign currency accounts and transactions of the customer can be checked, and the bank can pay wages and withhold consumer credit for the customer. Through a debit card, you can enable the withholding of water, electricity and gas bills at the bank, purchase financial products, funds, insurance, realize bank-securities transfers, bank insurance, etc., and enable mobile banking and online banking for self-service. wait. However, the best feature of a debit card is debit. In layman's terms, you can only use as much as you have balance, and there is no overdraft function.

3. The most essential difference between a credit card and a debit card is that it is a credit card. There is no need to have a balance on the card when using it for purchases. It is a form of credit provided by banks to their customers. As long as you repay in full before the next payment due date, no interest will be charged. If you repay 10%, the bank will charge interest on the remaining amount at the loan interest rate without charging penalty interest. Therefore, a credit card is a credit and financing tool. Due to its international status, it provides an extremely convenient channel for personal financing and payment.

4. However, some customers do not understand the difference between the two, and there are many misunderstandings and even losses during use. Debit cards do not have credit functions and are very versatile, so banks generally only charge an annual fee of 10 yuan per year. The annual fee for credit cards is relatively high, usually 180 yuan per year. Depending on the customer's credit and overdraft limit, the annual fee for a credit card will also be different. There is no charge for withdrawing cash with a debit card, but high fees are often charged for withdrawing cash with a credit card. Debit cards can only use the balance on the card, but if there is a balance on the credit card, not only will there be no interest, but there will also be a handling fee if you want to withdraw it.

5. The passbook is the certificate of savings deposits. It only has the functions of depositing, withdrawing and transferring savings deposits. Because it cannot be used in different places or withdraw money at self-service equipment, it is often paired with a debit card. Many customers feel that after opening a debit card, it is not as intuitive as a passbook, so they add a passbook to make it easier to view transaction records.

So each has its own purpose.
