The reasons for abnormal bank card transactions are:
Report loss of frozen card, degaussing of bank card, insufficient balance, wrong transfer card number, etc.
If it has been frozen, you need to find out the reason for freezing and then apply for thawing. If it has been degaussed and cannot be read, you need to go to the bank to renew the magnetism or change the card. Another possibility is that the bank card has the risk of being stolen, and the banking system has monitored it. Common reasons are: the bank card has been stolen, the cardholder has never swiped the bank card, and the risk of swiping the card is high. After the bank card service is suspended, I need to go to the counter with my ID card to handle related business.
It should be noted that bank cards cannot be put together with mobile phones, televisions, stereos, microwave ovens and other magnetic field appliances, which is much better, and multiple bank cards and passbooks cannot be put together.
Don't panic, but don't sit idly by after the abnormal transaction of bank cards is suspended. You can call the bank's customer service hotline and ask the customer service to help you find out the reason for the abnormal bank card transaction.
