TapWren Tag

A 50 mm sticker that turns a doorway into a time clock. Your crew taps it with the phone already in their pocket — no app, no login, no badge.

Each tag is encoded with its own address at the factory and then write-locked, so it cannot be rewritten. Minimum print run is 30 per design. A tap needs a phone with NFC — every iPhone since the XR and effectively every Android.

From the box to the first tap

Three of these happen once. The fourth is the only one that repeats — and it is the only one your crew ever sees. Moving a tag to another room is a change in the dashboard, not a new sticker.

  1. We do this

    It arrives encoded

    Each tag leaves the factory carrying its own address, locked so it cannot be rewritten.

  2. You, once

    Stick it up

    Beside the door people already walk through. Chest height, on anything that is not metal.

  3. You, once

    Assign it to a place

    Tap it while signed in as admin, pick the location, and the tag becomes that place.

  4. Your crew, every shift

    They just tap

    Clocked in, at that location, on the record. Their supervisor reviews it before payroll.

The coil is what you’re paying for.

The chip inside is a speck about a millimetre across. The antenna coiled around it is the part that decides whether tapping feels effortless or annoying.

A small coil forces people to aim. A tag people have to aim at is a tag they stop using.

What arrives

Tags on a liner sheet and a card that says what to do with them. Nothing to charge, nothing to configure, nothing to install.

Coming later: the cryptographic version

A second version built on the NXP NTAG 424 DNA chip is planned. That chip signs every tap with a rotating code, so a copied link cannot clock anyone in from somewhere else. It is not what ships today — today’s tag carries NTAG 213, and presence is backed by the registered device, the location signal and supervisor review rather than by cryptography.

Still being confirmed

  • Antenna size. The printed label we priced carries a 20 mm antenna, which makes people aim. We have asked our manufacturer whether the same print can go on a 38 mm inlay. The read ranges above are what a 38 mm antenna delivers, not what we have in hand.
  • Serial and chip pairing. Printing the serial and encoding the chip are two separate production steps. We want it in writing that both come from the same row of our list.
  • Pricing. The prices above are drafts. They were derived from the manufacturer’s NTAG 424 DNA line item, not the NTAG 213 one.
