Everything about QR codes, in one place

What they are, which type to use, how to design one people will scan, and how to connect it to your tools.

What is a QR code?

A QR (Quick Response) code is a square barcode that phone cameras can read. It holds up to a few thousand characters, usually a web link, and still scans when up to 30% of it is covered or damaged, which is why you can place a logo in the middle.

Static or dynamic?

Static

Your content is stored in the pattern itself. Free, works forever, but can't be changed or tracked.

Dynamic

The pattern holds a short link we redirect. Change the destination anytime and see every scan.

Static vs dynamic in 45 seconds.

Design tips that keep codes scannable

Keep dark dots on a light background with strong contrast. Leave a margin around the code. Print at least 2 cm (0.8 in) wide, and bigger for every metre of scanning distance. Keep logos under a fifth of the code's width.
