Dear Jivko,

We have noticed activity with fraudulent credit
card orders.

This is what we did:

1) Do a address verification on the street adress
and zip (will only work with us banks from visa).
2) get a voice authorization.
3) If you think you need to, get a fax copy of the
front and back of the credit card with a signature

usually the fraudulent orders will not return a
voice authorization call.

Hope that helps,
Dev
