I want to have a user enter their name, address, and credit card information. With that information would it be possible to get the information the credit card company has so i can compare it against what they entered? I have found something like this on googles XML API (
http://code.google.com/apis/checkout/developer/Google_Checkout_XML_API_Tag_Reference.html#tag_avs-response) but they want $.20 a transaction from what i can tell. Dose anyone know of a way to do this check securely for free?
