A QR code for posters that you can still change after printing
The posters are printed, and the sign-up page has just moved to another address. If the QR code pointed straight at the old page, the print run is ruined. If it pointed at a short link, you only change where the link goes.
Why a short link is better
A yoy.fyi QR code encodes an address like https://yoy.fyi/fest. You decide where it redirects on the link's page, any time, in the edit form. The printed code stays the same.
A short code also makes the QR simpler. Less data means fewer tiny squares, and it scans better from a distance.
Formats for print
The link's page offers two:
- a 1024 pixel PNG, for flyers and social media;
- an SVG, which is vector, for large formats. It scales without losing quality, which keeps print shops happy.
Colours and caption
In the QR colours and caption block you can pick the colour of the code and of the background. yoy.fyi won't let you make a light code on a dark background or colours with too little contrast, because many phones simply can't read those.
You can add a caption under the code, like "Scan me" or "Register". The caption exists only in the SVG.
Count scans apart from clicks
Make a separate short link for the poster. Its page on yoy.fyi then shows only poster scans, apart from Instagram clicks. Add a tag like ?utm_source=poster to the address it points to, and your site's own analytics will see those scans too.
Test before printing
Scan the code from the screen with two different phones, then from a proof print at the distance people will see it. On a poster, keep the code at least 3 by 3 centimetres, and bigger for posters read from far away.
