From the perspective of cardholders, online payment is considered to be the most risky of several payment methods for credit cards, because malicious people may use phishing, eavesdropping on Internet information, and fake payment gateways to steal user information. When paying online, you need to enter the card number, the validity period of the credit card, the number of Visa CVV2/Mastercard CVC2/UnionPay CVN2 next to the signature column on the back of the card, and the online transaction password. Sometimes you need to enter your name, a verification code randomly generated on the web page, etc. After the input is complete, click Submit to complete the online payment. With the development of the Internet, the security of online payments and credit card payments has gradually improved, which has also created a trend of online consumption.
