You can buy on some shops where your card MAY be checked IF it is registered on the VBV programme.
Not every merchant accepts non-vbv cc. I can renember something about 3D Secure. I renember that I could not go through the payment with a non-vbv card. I had to use an AMEX.
The problem is when the AMEX cannot be used.
But further solutions can be executed.
