Precautions:
The normal consumption operation is suspected of poor credit card swiping, and the bank may require the cardholder to provide proof of consumption flow. If the cardholder can't provide the voucher, he may be identified as a high-risk user by the bank. In order to avoid risks, banks may take some risk control measures for cardholders.
If illegal card use is detected by the bank, the cardholder's card will be tested for risk control, and in severe cases, the card will be frozen, and the cardholder will be required to pay off the arrears in the credit card at one time.
