The card arrived promising a service nobody was running
The first draft said "scan if found for safe contact". Nothing was connected to it, so the promise was empty.

Rexi's Vibe Tag
Rexi is a very small dog. She sleeps all day with her tongue out. Then she runs very fast for no reason. She barks at hello, and she barks at goodbye.
This is a demo card. Rexi's real tag is on Rexi. Nothing on this page is connected to her, and no address or phone number is printed anywhere on it. It is here so you can make one for your own pet.
Build your card
Pick a front. Pick a back. That is the whole card.
Card Studio is the same free app that printed the original. It opens holding this card, both faces, and you can change anything before you print.
Is this a tag for your pet?
Yes — show me how to put my pet's details on it
You can put your pet's details on the tag itself, so a finder reads them by tapping it. Here is the short version.
- Print the stick your NFC tag here face.
- Stick a 25 mm NTAG215 sticker in the printed circle. Ink and NFC chips do not mix, so the chip goes on after printing, never through the printer.
- Write your details to the sticker with any NFC writer app, or with Card Studio's Chip panel.
What to write, and why it is private i
Write a link that carries the details inside itself, after a #:
https://mrdirno.github.io/vibe-cards/tag/#name=Rexi¬e=Barks+at+hello&email=you@example.com
The part after the # never leaves the phone that read it. There is no
database, no account and nothing to sign up for, because there is no record
anywhere to look up. Only someone holding your tag can read it.
Put an email on it, or a phrase, or nothing at all. Do not put your street address on a pet tag. An address on a collar tells a stranger where an empty house is. An email reaches you just as fast.

Where the pictures came from
Every face is generated artwork, not a photograph of Rexi. No real person appears on any of them. The words come from what her family said about her: she sleeps a lot, she gets sudden bursts of energy, and she barks when people say hi and bye.
The log

The chip cannot go through the printer, so the card makes room for it
NFC stickers are not inkjet safe. The card prints a 25 mm circle and you stick the tag on afterwards.

Seven faces, because choosing the picture is the whole job
Other cards here have two fixed faces. A pet tag has one real decision, so this page lets you try every pairing.
