US merchants implementing Paypal PayFlow Pro can enroll in the Verified by Visa program.
This is slightly more complicated than other payment processing systems we offer, in that the credit card transaction takes place on your own server, and hence you require an SSL certificate on your site.
Enabling Payflow Pro will force the second phase of checkout to
take place on a secure (https) connection. For instance, with Payflow
Pro enabled, you will find that after viewing the contents of the
cart and clicking checkout, the URL changes from
http://www.yourstore.com/cart.php
to
https://www.yourstore.com/cart.php
If you do not yet have a certificate installed this will fail. To purchase an SSL certificate we can recommend www.thawte.com.
Now you just need to enter the information that PayPal sent you when you opened your account by going to your store admin and clicking on Edit Payment Providers, and you should be all set.
Please note that it is possible to use shared SSL space if your host provides for this, but you must be able to access the same database as for the rest of your store. We have provided more information about setting up on a secure server here
Please do read our guide here on credit card fraud.
That's all there is to it really - any comments on the set up can be posted on our Support Forum.
