Psst. Folks in Aus. The Telstra plastic pit covers? Newish ones? They have a little NFC icon in the corner.
You’d better believe that’s an NDEF-formatted [correction: unformatted but NDEF-capable] NFC card chip embedded in the plastic.

And oh yeah, it’s writeable.

@s0 “can be made read-only: yes” because fixing a rickroll should involve replacing a 20KG chunk of concrete

@s0 what can you 'write' into a NFC chip?
Show threads0 Is Not A SysadminMar 19, 2024
@luka I meant NDEF-formatted NFC. You can write plain text, URLs, contact cards, emails, wifi credentials, etc. Many will automatically open when scanned by a phone.

That is crying out for an Easter Egg hunt. Clues written to each NFC hinting where the next NFC can be found and people going around collecting the clues.

@s0 … I wonder how sanitized the NFC data is on the chain from “scan the ID”…

@s0 alternatively, free heavy-duty NFC cards (emphasis on the heavy)
