1, pay attention to protect your transaction password, and pay attention to the people around you when you swipe your card in a physical store; When entering the transaction password, cover it with your hands or other obstacles.
2. Take good care of the card. You should know that the credit card will have your corresponding information on it, so pay special attention. If you find the card lost, you must report the loss to the card bank in time.
Don't believe false information or messages. Don't click on the so-and-so complete and so-and-so link received on your mobile phone easily, so as not to enter the phishing website.
