before 1-2 years there was 1 trick which you could use for passing through the
security of the online stores that requires CVV2.
the problem was because of the default CVV2 numbers of Mastercard and Visa! :
MC's default CVV2 was : 202
VISA's default CVV2 was : 001
and there were alot of online stores that had the problem!
now there are not so much.and that's why I posted this now.
i did NOT found this problem. i just knew it.i think it's not a problem now because there are alot of new CVV2 security systems.
THIS WAS REALLY HIGH RISK SECURITY PROBLEM!
For now this is what i can tell you.
c ya l8r.
