Design your own
NFC tag.
A tag that does something when a phone taps it — puts the phone in sleep mode by the bed, shares the guest Wi-Fi, opens the manual, calls you if a bag is found. Any shape, any word, chip sealed in and programmed. Previewed live in 3D, printed to order in Melbourne.
Engraved reads crisper at small sizes (great for names) and takes a colour-fill nicely. Raised stands proud for a chunkier look.
Bambu Lab PLA Basic filament colours — the preview shows a matte-PLA render of your pick. Preview colours only; the exact filament shade can vary slightly from the render. Two-colour lettering is an AMS finish — tell us in the order notes.
The chip is sealed in the back of the tag. Tap a phone on it and it does what you chose: an automation (iPhone Shortcuts or Home Assistant run on the tag itself — no data needed, so a bedside tag can put the phone in sleep mode), a link, a call or an SMS. We program it before shipping; change it any time with a free NFC app. 25 mm round or 21 × 11 mm rectangular NTAG213 in stock, included.
Split-ring hole is Ø4 mm with a solid 3 mm+ loop so it won't tear. NFC chip pocket adds A$2 — 25 mm round or 21 × 11 mm rectangular NTAG213 in stock, programmed before shipping. Made to order in 3–5 days. No licensed logos or characters.

How our tags are built
A solid one-piece plate — 3–6 mm thick — with your name, shape or logo either engraved into the face or raised proud of it, and a reinforced Ø4 mm split-ring hole so it clips straight onto keys, a bag, a backpack zip or a lunchbox. No assembly, nothing to glue. Interior counters of letters like O, A and e stay as clean through-holes.
Tap-to-open: the NFC chip pocket
Tick Add NFC chip pocket and a round recess appears in the back of the tag — the face with no lettering — sized Ø25.6 × 1.0 mm for the 25 mm NTAG213 sticker we keep in stock (the default — we program it before shipping). There is at least 1.2 mm of PLA over the chip on the reading face and 2.5 mm of tag all round it, and the pocket stays clear of the split-ring hole and the keyring lug — the studio raises the size for you if the tag is too small, and tells you when a shape is too narrow. Print it as exported, drop the tag in afterwards, and a phone reads it straight through the plate. 25 mm NTAG213 sticker, in stock — we program it before shipping (+A$2). Point it at your website, a vCard, a lost-and-found page or your Google reviews — Read the full guide: NFC tags, reading, writing & best practice → Standard stock: the 25 mm round NTAG213 sticker and a 21 × 11 mm rectangular NTAG213 sticker — both included. Need a smaller chip? Put it in the order notes as a special request and we'll size the pocket for it.
Great for
Name keyrings, kids' bag & backpack tags, luggage & suitcase tags, gym-bag and water-bottle tags, gift favours and market stalls. Choose any colour PLA — or ask us about a two-colour AMS finish so the lettering pops.
