Landlord, check whether your credit card is a magnetic stripe credit card or a chip credit card. If it is a magnetic stripe credit card, it is a credit card transaction. If it is a chip card (that is, there is a chip on the card), you can only insert the card for transaction, but not swipe the card. So the display format is wrong, maybe the card is used in the wrong way.

Another possibility is that your credit card only supports overseas use, not domestic use. For example, CCB has issued single-currency cards such as JCB (such as Transformers 4 theme credit card and JCB Japan travel credit card), VISA or MASTER (such as EMV credit card, Olympic card and World Cup card). ). Without the UnionPay logo, domestic merchants generally cannot use it, and can only use it in overseas merchants or Haitao.

If none of the above is true, you should call the customer service hotline for specific inquiries. Welcome questions.
