Print your own QR decal, free, on any printer

You do not have to buy a vinyl kit to use QR calling. The decal generator draws your code at its real physical size and sends it to whatever printer you have. Here is how to get one that actually survives a windscreen.

Buying a vinyl kit is the easy path, and for a car that lives outdoors it is the right one. But nothing about QR calling requires it. The decal generator on your QR dashboard draws your code at its real physical size and prints it on whatever you have — and a paper decal behind glass works perfectly well.

The three sizes, and which one you want

2" × 12" panoramic strip. The default, and the one most people should pick. It sits along the bottom or top of a windscreen, or across a gate, where a square sticker would block a view.

3" × 12" heavy-duty strip. The same layout with an extra inch of height, which buys a bigger QR and a bigger wordmark. Pick it when the code has to be readable from across a car park rather than from arm's length — a shop shutter, a compound gate, a fleet vehicle.

4" × 5" door plate. A portrait block for beside a doorbell or on a flat door. There is also a 3.5" square cut for vehicles where a strip will not fit.

Vehicle or door changes more than the wording

The generator asks what the decal is for before it asks anything else, and the answer changes the whole thing. A vehicle decal reads need this vehicle moved? and offers wrong parking, blocked gate, lights left on and tow warning. A door decal reads digital doorbell and notice and offers visitor, courier, building maintenance and urgent notice.

Same code, same account. Print both.

The colour cuts

Clean vinyl is black on white and uses ordinary black ink, which makes it by far the cheapest to print and the easiest to read. Start here.

Safety yellow is the high-visibility cut: black on amber, with the brand rule and the URGENT block in lime. Use it where the decal has to be noticed rather than merely found — a gate, a loading bay, anything at night.

Stealth dark is near-black with white type and a lime rule. It looks best on a dark car and is the most expensive of the three to print, because it covers the whole sheet in ink.

The one real constraint: a 12-inch strip does not fit across A4

A4 in landscape is 11.69 inches wide. After any sane printer margin, a 12-inch strip has to come down by about 7%.

The generator makes that your decision instead of the print driver's silent one. Pick A4 and it prints at 11.2 inches and says so. Pick Legal/Folio or A3 and you get the exact 12 inches — A3 has room to gang two strips on one sheet, which is what to ask a print shop for if you are doing several.

The preview is true to size throughout. What you see is the proportion that comes out.

What to print on, in order of how long it lasts

  1. Self-adhesive matte vinyl, cut to size. This is what the posted kits are. Years outdoors.
  2. Ordinary paper, laminated, then taped inside the glass. Cheap and surprisingly durable — the glass does the weatherproofing.
  3. Ordinary paper, behind the windscreen. Free, works today, and will go yellow in a few months. Perfectly good for trying the product.

What does not work is unlaminated paper stuck to the outside of anything. One monsoon and the code is unreadable, which for a QR means it does not scan at all rather than looking a bit tired.

Two things worth checking before you print

Print at 100%. "Fit to page" silently rescales the sheet, and a decal that arrives 8% small is a decal whose measurements you can no longer trust.

Scan it before you stick it. Open your own camera, scan the printed code from the distance people will actually stand at, and check the page opens. A code that is too small, too pale or printed in draft mode fails in exactly this test and nowhere else.

The optional label row

There is a field for a plate number or a flat number — KL-07-CC-1234, Flat 402 · Main gate. Leave it empty and the row does not print at all.

It is worth filling in for a door or a gate, where it tells a courier which flat they have reached. On a car it is your own call: it makes the decal obviously yours, and it also puts your registration on a sticker in a car park.

When to just buy the kit

If the decal goes on the outside of a vehicle, on a gate, or anywhere it gets rained on, printed paper is a stopgap. The vinyl kits start at ₹249, arrive with calling balance already loaded, and are posted free anywhere in India — and if you would like to sell them as well as use them, that side of it is here.

Frequently asked questions

Is printing my own decal really free?
Yes. Creating the QR code and using the decal generator both cost nothing — you pay only for the paper or vinyl you print on.
Why does my 12-inch strip print at 11.2 inches?
A4 landscape is 11.69 inches wide, so a 12-inch strip cannot fit across it at any usable margin. Choose Legal/Folio or A3 in the sheet selector to get the exact 12 inches.
What should I print the decal on?
Self-adhesive matte vinyl lasts years outdoors. Laminated paper taped inside the glass is a cheap and durable second. Plain paper behind a windscreen works but yellows in a few months.
Which colour should I choose?
Clean vinyl — black on white — is the cheapest to print and the easiest to read, so start there. Safety yellow is for gates and anywhere the decal must be noticed. Stealth dark suits a dark car but uses the most ink.
Do I need to put my number plate on it?
No, the label row is optional and does not print if you leave it empty. It is useful on a door or gate so a courier knows which flat they have reached.

Take your phone number off your windscreen

Almost every car parked in a city has a phone number on the dashboard, and almost nobody thinks of it as published. It is. Anyone who walks past can photograph it, and from then on it is theirs.
