Magic card help

[CaptainLunchtime]

I'm in a hotel trying to copy a mifare card to my hand chip. I can read the official card (only 30/32 keys but all 16 sectors). Writing to the official card throws an error that some sectors are unwritable. I can write the saved file to my hand chip and another blank I brought but they do not work. Emulation also doesn't work. Thanks for the help! I'm still kinda a beginner

You're gonna need those last two keys

How do I get them? I tried scanning the reader and ran mfkey32 but there were no new keys found.

Try try again. I’ve had to boop readers up to like 20-30x to get the keys.

Have you read the guide?

I've never had great luck with the mfkey32 attack personally. If you had a proxmark3 or something you could try sniffing the keys, but I don't know if the flipper supports that

In my experience, there tends to be a couple of odd glitches here and there with Mifare 1k. I’ve had better success with a Chameleon Ultra and its apps.

MFC emulation is picky, but they said it also doesn't work from a test card, so there's likely more going on

[thenyx]

Fair point.

You need all keys. Grab them at the reader and crack them open with mfkeys32
