Visa/Mastercard mandate CVV number

Hi there,

I received an email from eWay a few days ago to inform me that on the 1st April 2012, Visa and Mastercard mandated that all online transactions must include the CVN/CVV2 number.

eWay performed a check on a website that I have developed which uses CS-Cart Pro v2.1.2. They have informed me that the CVN field in the checkout is not being passed to them correctly. Apparently there needs to be some change in the code so that the field is passed to the correct URL.

Is anyone aware of this change and can help me understand how to fix the field?
