Phone-call QR code generator
The smallest, toughest QR payload there is: scan, and the dialer opens with your number ready. Because the content is tiny, the code stays scannable at sizes where other codes give up — 18 mm tags, helmet stickers, equipment plates, "in case of emergency" labels.
International format. Spaces, brackets and dashes are stripped automatically.
Built for abuse
A tel: code is usually version 1–2 (21–25 modules). At 18 mm the modules are
still ~0.6 mm — printable on a home label printer and scannable scuffed. Pair it with error
correction H in the studio and a third of the code can be scratched off before it fails.
This is the right type for anything that lives outdoors or on a keychain.
Where it beats a vCard
A vCard saves a contact; a phone code starts a call. For emergency and service use ("machine broken? call us", a dog tag, a lone-worker badge) you want the call, not a contacts entry. It is also a tenth of the data, which means a far tougher code at the same size.
Error correction H, colours, or a sheet of asset tags?
