Hi,
I am doing some work on mifare 1K
I am trying to understand the last part of block 0
8 bytes manufacturer Data
Is there any specific way this is programmed?
Like:
Programmer ID
CID
ICR
Year
Quarter

In original cards last 2 bytes year and week. Other bytes have not an official meaning nor unofficial speculative meaning

I have original cards where the last 2 bytes can't be a year/week.
Would that mean that they were randomly generated or chosen by hand?
Also, for an identical manufacturer, I get different 'manufacturer data'. Some are the same among different cards but other are not.
