Why did China Merchants Bank pay online by credit card without entering SMS verification code?

Hello, in order to ensure the safety of customers' funds to the greatest extent, when you pay online, the risk detection system will ask you to further verify your identity when it finds that there are certain potential risks in your ongoing transaction. If you have reserved your mobile phone number, please click "SMS for verification code" in the authentication interface, and you will receive a short message containing verification code on the reserved mobile phone; If you have not reserved your mobile phone number or need to modify it, please call the customer service hotline at 4008205555 and ask the network transfer service specialist to set or modify your mobile phone number.

But this verification is not 100%, it is random.

If in doubt, please add enterprise QQ customer service 4008205555 or WeChat to WeChat official account "China Merchants Bank Credit Card Center" for detailed consultation.
