Ordinary cards are ordinary debit cards, which are essentially different from credit cards. The debit card is your own money, and the credit card was lent to you by the bank first. For security reasons, if you want to pay online, you must enable a debit card. The debit card itself has many functions, but it needs to be opened to use. You can go to the outlet to open online banking. Then set up and open online payment, SMS, password card and other functions.
Credit card, direct online payment, is automatically completed by the banking system and is a card-free transaction. If you pay by credit card, you need to fill in the credit card number, cardholder's name, card validity period, identification code on the back of the card and so on.
