Friends who often use credit cards should sometimes encounter this situation, and the network will be abnormally blocked when spending by credit card. What should I do at this time? Will this affect the money in the credit card? Let Bian Xiao answer your question:

When spending by credit card, if the network is interrupted and the card cannot be swiped normally, then another way is to authorize the credit card manually, and the debit card generally needs to wait until the network or system returns to normal before accepting it.

If the credit card transaction fails, it may lead to an account error. Don't worry about this situation, because both banks and UnionPay have established corresponding error handling mechanisms, which will help you inquire about related transactions, adjust account information and ensure the safety of funds.

If you have any questions about the account transaction, you should contact the issuing bank in time to inquire about the transaction and provide relevant information so that the bank can confirm the problem. As far as processing time is concerned, please check the progress with your issuing bank.
