Where can I find more information about the data found on the NFC cards within Amiibos? I've been using an NFC reader to collect dumps from an Amiibo and I'm regularly receiving 540 bytes of data, but it appears to be encoded. I've also compared a dump from before/after making a small change to the Amiibo (after I fed the Amiibo a single item) and I noticed that while the majority of the data changes, there are large chunks of data that persist, leading me to believe that this is structured data and not an encrypted blob of data. I would share the data I've collected, however I want to know what the data is before I upload it, in case it contains sensitive info, e.g. my gamer ID.
