![]() ![]() But I changed it to see what will happen. ![]() I know that when changing the service code, the CVV1 is also changed (DES encryption of PAN, Exp Date and Service code = CVV1). Then I did some research and found this : after typing the PIN i got the withdrawal screen, pressed on the lowest amount then the ATM said "Service is Unavailable for this card". I cloned my own CC (201 / chip) on blank Magstripe card and went to the ATM. I thought this is extremely dangerous and went to the wild to check it on my own card(201 / Chip and Pin) and here is the outcome: and the whole EMV is irrelevant in this case. What criminals are doing is cloning track 1//2 on Mag cards with blank/unreadable Chip, this will cause the POS to fallback to Magstripe transaction. When the POS cant read the Chip, it will fallback to the Magstripe. ![]() The problem that each card STILL has a Magstrip in case EMV is not working(Merchant don't wanna lose customers). To be honest it look like they are not doing enough to stop fraudulent activity with Credit Cards.įrom my understanding, each card has an smart chip that use encrypted data, this to overcome the Magstrip plaintext. I'm new to this topic and I found it very interesting how all the payment system is currently working.
