Avangate does not request highly personal information for placing the order (ex: Social Security Number).
However, our system does support a security system called 3D Secure, which is provided by Visa and participating banks. This system requires that, after the card number is filled in, the owner of the card is authenticated by supplying a password to the authentication server of his bank (the password is previously set by the cardholder for on-line transactions only). More information about how this works can be found on Visa’s website.
After placing the order, you might be directed to a webpage from the issuing bank, which asks you to enrol in this program. As part of the enrolment for this service, the bank may ask for information like the social security number, birthday, and certain passwords/security answers.
