Mifare 1k emulation problem #111

Closed mitmarcus closed 1 year ago

mitmarcus commented 1 year ago

Keyfob Im trying to copy is a "NXP MIFARE"

The reader is a Salto Modular XS - EU Wall Reader

Card is successfully read and the keys are aqquired, however upon emulation the reader always denies the chameleon. Running mfkey32 results in keys that are always "FFFFFFFFFFFF".

I have the binary dump, but can't upload it here. Am I missing something to emulate it?

Hi. Do you have a proxmark to sniff what happens? We have same issue and we want to check if the root cause could be the same. Thank you

This is very probably the same as #110 so I will close this one as duplicate and invite you to discuss it on the other issue, thank you!
