About the Mini NFC Tag

This is our smallest-format NFC tag, purpose-built for makers and jewellers who need to hide an NFC chip inside a finished piece rather than stick a visible tag on the surface. It's commonly embedded during 3D printing (paused mid-print to drop the tag in), set into resin jewellery, or fitted into custom smart rings — all while staying small enough to disappear into the object.

Common Use Cases

3D-printed smart objectsPause a print partway through, embed the tag, then resume — the finished piece taps to open a link.

Custom jewellery & smart ringsEmbed inside resin or metal-adjacent jewellery for a tap-to-reveal digital message or profile.

Small gift & keepsake tagsHide inside a small gift or keepsake for a tap-to-unlock personal message.

Compact product authenticationEmbed discreetly into small products where a visible sticker would spoil the design.

Frequently Asked Questions

Will this work if fully embedded (no visible tag)?

Yes, as long as it isn't embedded directly against metal — resin, plastic, wood, and most non-metal materials don't block the signal.

How close does a phone need to be to read it?

Typically 1–3cm given the smaller antenna size — slightly shorter range than our full-size cards.

Can I still program it after embedding?

Program the tag before final embedding for easiest access; NFC data can technically still be rewritten afterward as long as a phone can get close enough.
