MF Classic 1K UID Change

[Leonidas]

@Jirvin

Why are you looking for a card with a re-writable 7 byte UID?

@Leonidas

I have an implant with 7 byte UID, which is present in the Access Control database. Now, I’m trying to figure out how to make more ways of authenticating, since the implant is not always a rock solid solution, especially when the readers suck. The important thing to mention is that the HF readers in our scenario only authenticate based on the UID of the chip.

@Jirvin

It would be worthwhile putting your source card (the one you want to copy) on the proxmark and sharing the ouput of hf 14a info .

I have trouble scanning my Spark2 with PM for some reason, not sure why, phone reads it just fine, so does KBR. But I know the ID from the phone, so.

Let’s say I’d use the NTAG in my NExT for this scenario, doesn’t really matter.

Here's the requested output.
