14443-B write block data


My objectives:
1. Get a valid key(?) using "hf 14b snoop", followed by a "mfkey" function. (done)
2. Get the remaining keys using hardnested function.
3. Read sectors data. "rdsc"
4. Write some data to a block

Of course, obj 2-4 uses the "hf mf" function.

Seems like "hf mf" functions do not work with 1443-B tags?

Just using "hf mf" function to get my idea across.

Any suggestions as to how to go about using those functions or something similar? Did not find much on the "ISO 14334-B" forum tags.

Thank you!

Re: 14443-B write block data

...haven't seen a Mifare Classic card that uses 14443-B til this day...
