How to use credit cards:

Generally, a password is set. When you apply for a credit card, you can choose whether or not to have a password. When you make a purchase, the merchant must provide a POS machine to swipe your card.

When swiping a card, if you have set a password, you must enter the password and then sign the form printed on the POS machine. It is best to check whether the amount is correct.

Generally, if you swipe your card more than three times a year, the annual fee will be waived.

Pay attention to the settlement date when using it, it is very important for your credit. Taking the CCB card as an example, if the settlement date is the 10th, then the purchases made before the 10th must be returned before the 30th, and the purchases after the 10th must be returned before the 30th of the next month.

Another advantage of using a credit card is that it is free to swipe the card in other places. If it is a debit card, a handling fee of 1 will be charged for swiping the card in another place.
