QR codes are everywhere at events now, from menus to photo galleries — but how do they actually work, and why are they so popular? Here's a plain-English explainer, plus tips to make sure yours gets scanned every time.

What a QR code actually is
A QR code is simply a link in visual form. When a phone camera reads the pattern, it decodes a web address and offers to open it. That's it — no special app required on any modern phone.
Why they need no app
Because a QR code just opens a web page, guests don't install anything. They point their camera, tap the link that pops up, and they're on your upload page in seconds. This is exactly why participation is so much higher than with app-based tools.
Making your code easy to scan
Keep strong contrast between the code and its background, print it at a sensible size (at least 3 cm square for table cards), and leave clear space around it. Add a short instruction so guests know what they'll get when they scan.
Where to place them
Put codes where guests naturally pause — tables, the bar, welcome signs and near photo backdrops. The more visible and inviting the code, the more scans and uploads you'll collect.
Quick tips
- • Test your code on different phones before printing.
- • Use high contrast and leave a clear margin around the code.
- • Add a one-line instruction beside every code.
