I am working with Ultralight and DESFire tags using "hf mf snoop" and "hf mf list". Is there a resource that can help me to decode the output from the reader and the tag?
I have stumbled across different posts and source code which is helpful, but I'm having trouble finding anything definitive as a reference. I can buy an ISO spec, but I'm not sure which document is the correct guide to decoding these bytes.
Suggestions?
Thank you,

Following up on my old post, I ended up manually figuring out what different opcodes did, and starting keeping track in a spreadsheet. I've posted the spreadsheet at the URL below in case it is useful for anyone else:

This is not complete by any stretch, but should help other folks evaluating the output of traces.
Cheers,
