1. If you find that your bank card has been stolen, you should immediately call the bank customer service hotline to report the loss or freeze the card account to minimize your losses.

2. In order to prove the fake card transaction, the cardholder needs to prove that the real bank card was held in his hand when the transaction involved occurred. The correct way is for the cardholder to go to the nearby bank counter, ATM machine or POS machine for credit card transaction at the first time, which can be used as strong evidence to prove the fake card transaction.

3. Report the case as soon as possible and retrieve the transaction video. When the cardholder reports the case, the public security organ will retrieve the video of the transaction involved.

4. Call the bank customer service to apply for a refund of the stolen amount, and the bank will finally give a clear answer through investigation.
