Tap a vault. See what's inside.
CardFinity is a free, private card-tracking app paired with 3D-printable smart vaults. Hold your phone to the C-Badge on any vault and its contents open instantly.
Track. Organize. Protect. Infinity.
"Where is that card?" Every collector knows it. You own it; you just don't know which box it's in.
01
Stick the tag
Press any NTAG213 or NTAG215 sticker into the 25 mm cavity on the front of the vault. That's the C-Badge.
02
Link it
Open the vault in the app, tap Link, and hold your phone to the badge. The app writes the tag.
03
Tap to reveal
From then on, a tap opens that vault's contents on screen. Any NFC phone. Works with a box you already own, too.
The vault collectors were already asking for.
We read every comment and rating on the three most-printed card boxes on MakerWorld, 22,600 downloads between them. The quotes are verbatim.
What you own, where it is, what it's worth.
Tap to reveal
Hold your phone to the C-Badge on any vault; its contents open on screen.

Raw and graded
Grades and cert numbers tracked per slab. Each slab gets a numbered slot.

Matte, blocky, printed at home.
Nine vaults: three sizes, each in a Raw, TopLoad and Graded version. Every vault shares a footprint family so they stack and lock, and all include divider grooves and print profiles. Soft-sleeved cards fit the Raw vault. Hard toploaders do not — they need the TopLoad vault. Graded slabs have their own.
| Capacity | Deck Vault | Card Vault | Mega Vault |
|---|---|---|---|
| Soft-sleeved (Raw) | 100 | 200 | 400 |
| Hard toploaders | 20 | 45 | 90 |
| Graded cards | 8 | 18 | 36 |
01
A lid that stays on and never scratches a card
Neodymium magnets hold the lid instead of friction: four per lid on the Deck and Card Vaults, six on the Mega Vault. It snaps shut, lifts with a fingertip, and never touches a card edge. Drop the vault or turn it upside down and the lid stays on.
02
Stack and lock
Ferrite discs in the floor and lid lock vault to vault, so a stack on a shelf does not slide and a tower of Deck Vaults moves as one piece.
03
No glue, no supports
Magnets are the only hardware: 4 × 4 mm neodymium and 25 × 4 mm ferrite. About $1.20 for a Deck Vault, $1.70 for a Card Vault and $3.00 for a Mega Vault. One bag of each covers all nine vaults with spares. Neodymiums press in after printing. Ferrites are embedded during the print. Print the Magnet Size Tester first. No supports.
04
Soft sleeves in Raw. Toploaders in TopLoad.
Soft-sleeved cards fit the Raw vault. Hard 3″×4″ toploaders do not — they need the TopLoad vault. A Yu-Gi-Oh! shim is available for smaller cards.
05
Works with any box
Stick a tag on a box you already own and it becomes a CardFinity vault.
Color the stripe and the badge round.
Two regions are set up to paint in Bambu Handy. The center stripe wraps all four sides. The badge round sits on the face, around the C-Badge. Blue in the diagram is what you paint. The body stays your base filament.
Center stripe
A band around the middle of the vault, paintable on every side.
Badge round
The ring around the C-Badge, painted on its own.
Bambu Handy
Assign the colors in the app before you print. The rest of the vault stays the filament you started with.
Print it your way. Licensees can sell it under their own name.
Body color, painted stripe, lid pattern, and the badge on the NFC tag are yours to change. Commercial licensees can sell finished vaults under their own name and logo, with a "Designed by CardFinity, Manufactured under License" badge. The tag still opens the CardFinity app.
Early Bird seats are priced below the standard tier.
Every tier includes the Print & NFC Setup Guide, magnet caps, insertion jig and Magnet Size Tester. Model files ship the day after the campaign ends.
Stretch goals
Stretch models release to backers first. The Display Stand goes free for everyone 90 days after the campaign ends. The Low Profile Raw Vault and Lid Pattern Pack stay backer-exclusive.
Back the campaign on MakerWorld.
The campaign is in public preview. All nine vault models are printed and tested. Files ship the day after the campaign ends. The app and Pro add-on codes are targeting 90 days after that.
Same tags. Same local-first idea. Applied to cards.
FINITY Labs is Gavin Stevens. COINFINITY, the NFC-tagged coin-stacker system, funded on MakerWorld in 2025 at 570% of goal. The models shipped on schedule, the app is live, and the store has been running since. CardFinity is the second product in the family: same tags, same local-first app, applied to cards.
In 2016, Gavin won $100,000 on Intel's America's Greatest Makers for the PowerBobber, a wireless Bluetooth fishing bobber. Watch it here.
