If the credit card has a limit and cannot be used, you need to ask the bank to cancel the payment stop status and restore the card's use authority before it can be used normally. The credit card cannot be used for the following reasons:

1. The credit card is not activated, the chip is damaged or the card has expired.

2. If the credit card limit is insufficient, the credit card consumption needs the available limit ≥ the commodity price. If it is lower than the commodity price, the transaction cannot be successful. You need to return the credit card or apply to the bank for withdrawal.

3. If the line of POS machine is busy or faulty, you can swipe your card later or pay by other means.
