First of all, you need to know whether the card has been activated and a password has been set. If the card status is normal, you should be able to conduct transactions. If the data does not exist, you can check again to see if the transaction method is correct. If you have a credit card with an IC chip, you must make the transaction by inserting the card and reading the IC chip. If swiping the magnetic stripe to read the card information is not possible, the machine will prompt an error. Also, check to see if the card in your hand has the UnionPay logo on it. Some card types only have the VISA or JCB or MASTER international credit card organization logos, but do not have the UnionPay logo. This kind of card can only be used abroad, and domestic UnionPay card swiping machines cannot be used.
