Second, the card does not support transactions. For example, the card with VISA single logo /JCB single logo does not support UnionPay transactions, nor does it support some online transactions.
Third, there is nothing wrong with the card. If the signal of POS machine is not good, the off-line transaction will fail.
Fourth, the IC chip credit card will not be used if the cashier still operates the transaction by swiping the card instead of inserting it, because UnionPay has turned off the downgrade transaction function.
Fifth, some overseas websites do not support domestic credit cards or CCB credit cards.
Sixth, the credit card limit is insufficient.
This means that the credit card is valid until May 2025. You need to change the card then, and you can't continue to use it.
