[Muscle] General contactless read/write

[Robin Helgelin]

Hi,

I'm new to contactless cards, I've only worked with memory cards and
SCM Micros own API.

I'm trying to get a SDI010 reader working with Mifare 4k. So far I'm
managed to get authentication and basic read working.

However, I don't really understand this with sectors, blocks, msb,
lsb, etc when it comes to read/write commands and I'm having a hard
time finding good documentation.

What I need to do is simply to write 144 bytes to the card and be able
to read them back again :)
