QR codes that outlive the print run.
Every Smart Link has a QR code. Style it, download it, print it - then change where it points whenever you like. Try it: the code below works.
QR code
urx.si/demo?src=qr
Locked to H while a logo is on, so the code still scans.
Scan it - it works.

Why a URX QR code keeps working.
A normal QR code has the destination baked in. A URX QR code points to your Smart Link, so the destination lives in URX - where you can change it.
Static QR
QR → acme.com/summer-menu
The menu changes, the posters are wrong, and you reprint.
URX QR
QR → urx.si/menu → acme.com/autumn-menu
Edit the destination in URX. The same posters now open the new menu.
Codes that scan - try these.
Each of these is the same live code. Point your phone at any of them.



Everything a printed code needs.
PNG and SVG
PNG for quick use, SVG for print - sharp at any size.
Your colours
Pick foreground and background colours with enough contrast to scan reliably.
URX mark in the centre
Add the URX mark to the middle of the code; URX raises error correction so it still scans.
Quiet zone kept
The blank border scanners need is always included in downloads.
Error correction
Choose L, M, Q or H depending on how rough life is for your print.
Scans in your analytics
Codes downloaded from URX carry a scan marker, so each link counts its QR scans. Scans are clicks too, broken down by country and device.
Printing tips.
1Size
At least 2 × 2 cm for close-up scanning; about one tenth of the scanning distance for posters.
2Contrast
Dark code on a light background. Inverted codes don't scan everywhere.
3Test
Scan the final proof with both an iPhone and an Android phone before printing.
