Call My Family

A tag for a child’s backpack or keyring

Scan a side. Call a parent.

Call My Family is a printable, 3D-printed tag. Each side has its own QR code, labelled PAPA on one side and MAMA on the other, so a young child can tell them apart. Anyone with an ordinary iPhone or Android camera can scan a side and gets a prompt to call that parent.

Tags are not for sale yet, and nothing has been printed yet. Check back here to be told when they are available.

How it works

  1. A tag sits on a backpack or keyring. One face says PAPA, the other says MAMA.
  2. A child, a teacher or a finder opens the camera on an ordinary phone and scans one side.
  3. The phone offers to call that parent. Each QR code holds only a telephone link — there is no app to install.

Privacy

There is no account and this website does not store phone numbers. A scan works offline and does not depend on a server: the QR code itself contains the telephone link. The DEMO images on this page use placeholder numbers only. When tags are made to order, parents would supply their own numbers; that order flow is not built yet.

Prototype designs

Floris van Lieshout made the first designs on 11 November 2026, in two sizes: 60×60×4 mm and 30×30×3 mm. They have a white base, flush black two-colour inlays, and rounded edges. The ring hole sits inside the corner, so nothing sticks out; a small-tab variant also exists.

These are DEMO renders with placeholder numbers, not photos of a printed tag. The first design previews encoded real phone numbers, so they stay off the site. Every QR face has passed digital scan tests (blurred, downscaled and angled). Real phones have not been tried yet, especially on the 30 mm size.

What comes next

A test print on a Bambu H2C, then scan tests on real iPhones and Android phones, with extra attention to the 30 mm tag. After that, child-safety checks — including small parts, and no neck cords — and, only if those hold up, a personalised order flow in which parents supply their own numbers.
