Credit card swiping was refused for the following reasons:

1. The line used by the card reader is busy or faulty.

2. If you spend money abroad, you may encounter network problems. I suggest you apply for a different brand of credit card (if you already have a VISA card, you can apply for a MasterCard) in case of emergency.

3. Maybe the magnetic stripe on the back of the card has been demagnetized or the card has been damaged. Please call the 24-hour customer service hotline to apply for card replacement.

4. It is possible that the credit card limit has exceeded the available limit, and credit card consumption will be carried out after repayment.

5. Please call to see if check card is working properly.
