Could you share more details about the pass, or where you are in the world? It might help figure out which technologies are being used
It's
NXP - Mifare DESFire EV2 4k
The data sheet specifies that they do use NFC technology, so in principle it can be copied and transmitted from a smart phone. How to extract that data though? I’m not sure. That’s beyond my skills.
Their documentation also specifies that they may integrate smart card features that specifically prevent copying by using cryptographically secure handshakes. In that case, if your card uses such features, it would be practically impossible. It depends on exactly how they are using it and I’m not sure of that.
Think of it like how you can do NFC credit card payments, but you can’t trivially record and replay the communications. You would have to know the secrets embedded in the chip in the card. Depending on the features they use it might be impossible to clone it with consumer hardware. Even if you can speak NFC and technically replay the information.
Okay, thanks for the info. Anyway I can confirm if it's encrypted or not?
