About this question
Every credit card has a smart chip using encrypted data, to evade the Magstripe plaintext. The issue is that every card contains a Magstripe if EMV is not functioning. In case the POS is unable to read the Chip, it will return to the Magstripe. Attackers are cloning track 1⁄2 on Mag cards with blank chips. This results in the POS to return to the Magstripe transaction, making the entire EMV irrelevant.
I thought of checking my card and I received this result. I cloned my personal CC (201/chip) on a blank Magstripe card. On visiting the ATM, I typed the PIN, got the withdrawal screen, tapped the lowest amount and the ATM mentioned, “Service is Unavailable for this card”. When altering the service code, the CVV1 is also altered. The cloned card of the CC worked fine in a single ATM machine.I attempted at altering the CVV1 to a random digit but it’s still working on that single ATM. Why is this happening?
