From the cardholder's point of view, online payment is considered to be one of the most risky payment methods for credit cards, because malicious people may steal user information by means of phishing, eavesdropping on network information, impersonating payment gateway and so on.

When paying online, you need to enter the card number, the validity period of the credit card, the Visa CVV2/MasterCard CVC2/ UnionPay CVN2 numbers next to the signature column on the back of the card, the online transaction password, and sometimes you need to enter the name and the verification code randomly generated by the webpage. After the input is completed, click Submit to complete the online payment. With the development of the Internet, the security of online payment and credit card payment has gradually improved, which has also blown up the trend of online consumption.
