newbie question about decoding

block#   | data         |lck| ascii

This was the dump from a tagit iso 15693 lable. Findafi gave me

[#] NoAFI UID = E0 07 C1 3F 26 09 56 44
[#] AFI = 0  UID = E0 07 C1 3F 26 09 56 44
[#] AFI Bruteforcing done.

Here are my questions

1) is the venor encoding the data prior to putting it in the rfid chip, or is chip encoding the data?
2) if its the latter, is there a utility that can decipher the encoding
3) if its the former, does anyone have a sense of what was used to encode it or a workflow to decode it.

Thanks,
