Why can't credit cards be used?

Credit card business is one of the sources of profits for banks. Therefore, in order to stimulate more people to apply for cards, major banks began to lower the threshold for card application and launched various preferential activities. Under normal circumstances, cardholders will not be restricted from using credit cards without reason. But recently, some users said that their credit cards suddenly could not be used normally. What happened? The following small series will tell you why!

1, transaction equipment obstacle

Credit cards can't be used, not only because of credit cards, but also because of equipment failure. You can try to restart the device and use it again after connecting to the network. At this point, if it is a device problem, it should be able to trade normally after restarting.

2. Illegal card use

You can continue to use the card only if you use it normally. If the user uses the card illegally, it will trigger the bank's risk control system, resulting in the suspension of the credit card. At this time, the credit card cannot be used normally.

3. Off-site consumption or consumption abroad.

In case of sudden consumption in different places or consumption abroad, it is easy to be controlled by the banking system, so risk control will be carried out for the safety of using the card. Faced with this situation, the cardholder can contact the customer service of the bank and explain that the normal card use can be resumed by swiping the card.
