The reasons why there is no response when swiping the card are as follows:
1. You cannot swipe the card for consumption if there is a limit. It may be because your card has made withdrawals or has been overdue for a long time, and the card has been frozen by the bank. It is recommended to call the credit card center to inquire about the specific situation.
2. If it is a MasterCard card, basically it cannot be used at domestic POS and can only be used at ATMs. It is recommended to apply for another UnionPay card to use at home and use MasterCard abroad.
3. If there is a problem with the card swiping device, you can try another one.
