Hello, i tried to read a NFC Card used in our business.


Any ideas on this one?

It looks a bit like this, when I use a flashlight to look through it.


Your card uses the Mifare Plus protocol, which is not yet supported by the Flipper, and the full reading may never be supported because this card uses strong cryptography that has no known attack vectors to date.

As a reference, if the card has a chip on it like a bank card, it is probably currently impossible to emulate - and using strong cryptography.
