It is a common means of credit card fraud, also known as cashing or swiping. Liars will borrow credit cards from cardholders in the name of helping them increase the credit card limit or gain points, and then use them to cash out or buy goods, and finally avoid repayment, resulting in the risk of credit card arrears and interest. If you find yourself cheated, you should call the police in time and contact the bank for handling. At the same time, cardholders can also upgrade and manage the credit limit through the bank's credit card limit management function or customer service hotline to avoid falling into the trap of credit card fraud because of the pursuit of credit limit improvement.
