Hello, we need to pay attention to the following points when making online payments:
First of all, you must ensure that your credit card password is not leaked. At the end of the signature line on the back of the credit card, there is a three-digit CVI password, also called a security password. As long as you know this password and credit card number, online payment can be completed. Therefore, after receiving your credit card, it is best to memorize these three numbers and then cross them off the back of the credit card. To avoid prying eyes from criminals.
Secondly, before using online payment, you must ensure the security of your computer. You must operate on a computer that is not infected with viruses or Trojan horses to prevent the password from being stolen by others; remember not to make it public in Internet cafes, etc. Use the credit card online payment function on the venue's computer.
Finally, confirm your payment permissions.
