Oh yeah, I already know how to program the tags, I’ve done that plenty of times :D
Since the tags themselves are sticky, I’d probably just stick one under a sticker. There probably isn’t any difference whether the tag is actually inside the sticker vs just under it. I’d just need a sticker that has an NFC symbol or a “scan here” field so that people know what to do!
Linking to happycow is a great idea! :D I could see something like “find a vegan alternative on happycow” stickers in front of other restaurants
NFC 213 and 215 tags are both capable of permanently locking, so that no new content can be written to them. I think NFC 215 even had the feature of setting up a password-protected write if you want to change it sometimes down the line :)
