If it is a China Merchants Bank credit card, in order to ensure the safety of using the credit card, we recommend that users:

(1) Keep personal information properly: When swiping your card for daily consumption, you should pay attention to using the card as much as possible. Keep the credit card within your sight, keep the signature, and do not transfer the card to others for use; when making non-face-to-face purchases, you should be vigilant about network security, online fraud, phone fraud, etc., and be particularly careful not to arbitrarily transfer the card number, expiration date, CVV2, etc. Leak credit card information to others; do not browse bad websites to prevent being attacked by network viruses, and do not register and pay through websites at will. If you need to shop online, try to pay through a regular website. It is recommended to activate the password verification service of an international credit card organization. (Ask the customer if there is any data leakage, and if so, handle it according to the existing process)

(2) Keep your mobile phone properly and update your personal information in a timely manner: Many online transactions require dynamic verification codes on your mobile phone After verification, our bank will also send credit card transaction reminders and other information to the user. If there are any changes to personal information such as mobile phone number, please be sure to modify it in a timely manner through the professional version of China Merchants Bank Online Banking or the customer service hotline.

(3) Carefully check the monthly credit card statement: If you find any questionable transactions on the statement, you can contact the bank immediately and the bank's professional processing personnel will assist.
