Their fucking protocol uses CBOR on APDUs. And no contact interface which means if you want to use it on your computer, too bad. You need to get 50€+ card readers instead of contact ones you can get for 10-15€

wtf CBOR
i hate CBOR
i have to deal with it at this time... blu esky protocol uses them
thankfully it's all handled by the library but the protocol is so shit that i basically had to write a little script to suck at the firehose to find out what are the important event kinds to capture for my aggregator, got like 12
Yes you heard that right, Coinkite is so incompetent they decided to use CBOR for smartcards with like a few KBs of RAM and slow processors
