With the development of information technology, the security of credit card online payment is constantly improving. In fact, online payment is very safe as long as you spend it on a regular shopping website.

Pay attention to the following points when paying online:

1. Please check the website first in the payment process to avoid visiting fake shopping websites and fake online payment pages.

2. Don't set the password too simply. Change the inquiry password regularly to reduce the risk of credit card theft.

3. The cardholder should set the online payment limit of the credit card.

4. The card number, expiration date and signature column number on the back of the credit card are important information for online transactions, so please keep them properly to avoid leakage.

5. Please log in to China Merchants Bank Online Banking Popularization Edition and download China Merchants Bank Netcom Shield to improve the security of online payment.

If you have any other questions, I suggest you call the customer service staff of the bank, hoping to help you.
