How to deal with credit card online shopping fraud?
1. When changing the contact information, be sure to contact the bank in time, so as to receive the dynamic password sent by the bank during online payment and ensure the payment safety;
2. Transactions should be conducted on reputable websites. Don't use unknown links. Now online phishing websites are rampant. If you pay by mobile phone, you should download the official software to avoid being crawled by phishing websites.
3. Protect your personal information and quit in time after using some software to avoid being stolen by malicious people;
4. In the process of online shopping payment, no matter what reason (such as refund, discount cashback, etc.). The merchant requires credit card information such as card number, expiration date and verification code. They are determined not to provide it. When returning goods online, you don't need the card number, password, expiration date, verification code and other information of the credit card, and the refund will be directly sent to the online store account or credit card;
5. Cardholders can reserve confidential information and passwords in the bank, which can not only verify the legality of overseas websites, but also verify the identity of cardholders, which can effectively reduce the risk of fraudulent use of bank cards on the network;
6. Once found cheated, immediately call the credit card customer service hotline and freeze the account to minimize the loss.
