What's the difference between Infineon M1 and NXP M1

SAK of NXP M1 can't change.
why?

Garage door system can distinguish between NXP M1 and Infineon M1.
And NXP M1 didn't work.
why,because of SAK different?

Thanks everyone.

Re: What's the difference between Infineon M1 and NXP M1

Magic card generation 1 SAK didn't change.
And generation 2 can change.
Is that it?

Re: What's the difference between Infineon M1 and NXP M1

I have no idea what you are trying to say.   SAK has nothing to do with magic generation 1.

have a look at  "hf mf csetuid h"  read the help,  and you can test.

Re: What's the difference between Infineon M1 and NXP M1

Writing a new block 0 worked in yr post #8 & #9,   definitly gen1.

Question is why you use atqa 0002,  compared with post #1.
