Interlocking Two-Part NFC Keychains

  • Two halves cut from one design and locking together — a puzzle join, a split logo, a heart, a map or any outline you send.
  • Each half is its own keychain with its own metal split ring, usable separately.
  • Embedded reprogrammable NTAG215 NFC chip: a tap opens a link, profile or programme without an app.
  • Full-colour print on both sides, edge to edge, with the cut following your own artwork.
  • Soft PVC, phthalate-free and EN71 child-safe. Standard 6 cm or maximum 8 cm assembled.

A single keychain says who you are. A two-part keychain says who you belong with — one half stays with you, the other goes to a partner, a member institution or a new colleague. It is the same object doing two jobs: an everyday keyring, and a physical token of a relationship that only reads correctly when both halves are present.

The shape is entirely yours. A puzzle join is the most recognisable version, but the same construction works for a split logo, a heart, a country or campus outline, a two-colour block, or any line your designer draws through the artwork.

Key Features

  • Two independent halves: each piece carries its own metal double split ring, so both can be used separately on separate keys. Together they form one continuous printed surface across the cut.
  • Any interlocking shape: the join is moulded to your artwork, not chosen from a template — puzzle tab, split logo, heart, map outline or colour block.
  • Reprogrammable NFC: an NTAG215 chip is sealed inside the PVC. Tapping a phone opens a URL, an event programme or a profile — and the target can be rewritten later without replacing the keychain.
  • Double-sided full colour: different artwork front and back, so one half can carry the identity and the other a message.
  • Two sizes: standard at roughly 6 cm assembled, or maximum at 8 cm and 8 mm thick — the largest this construction allows.

Shape ideas

  • Puzzle tab — partnership, twinning, mentor and mentee
  • Logo split down the middle — one half per department or per site
  • Heart, star or ring — retail, weddings, membership gifts
  • Map or campus outline divided between two locations

Common questions

How many do I have to order?

300 pieces, which is 150 pairs — each keychain is two halves. The one-off custom mould for your shape is included in the quoted price, and a re-order in the same size is cheaper because the mould already exists.

Does the shape have to be a puzzle join?

The join is moulded to your artwork, not chosen from a template — a split logo, a heart, a country or campus outline or a two-colour block all work as well as a puzzle tab. Assembled size is about 6 cm standard or 8 cm maximum at 8 mm thick.

What does the NFC chip do?

An NTAG215 is sealed inside the PVC. A phone tap opens a URL, an event programme or a profile, and the target can be rewritten later without replacing the keychain.
