A usage exception occurred.

The reasons why your credit card is restricted are as follows:

1. The bank suspects you of cashing out. If you often make multiple large integer amounts on a certain merchant's POS machine or make a large number of repeated online payments on a certain IP in a short period of time, the bank is likely to judge you as suspected of fraud and may We will use some means to limit your consumption limit to avoid possible losses.

2. Own problems such as credit card balance. Problems with the credit card itself include insufficient credit card balance, consumption exceeding the single (or daily or monthly) limit, credit card deactivation, etc. In this case, the credit card may not be able to pay.

3. The bank thinks your credit card may have been stolen. If there are some abnormal consumption records on your credit card, for example, if you usually only use your credit card to make purchases domestically, but suddenly have cross-border transaction records one day, the bank will suspect that your credit card has been stolen and will block the payment in time.

4. Bank reasons. Banks sometimes decline transactions, and if your credit suddenly becomes unavailable, you can contact the card-issuing bank to find out why. 5. Other reasons. Network or equipment failures may sometimes cause card swiping failures, so try several times before swiping your card.
