Static vs dynamic QR codes
A static code stores your content inside the pattern. It's free and works forever, but can't be edited after printing. A dynamic code stores a short link that redirects to your destination, so you can change it later and count scans — but it stops working if the service hosting the link stops.
Printing QR codes that scan reliably
- Use dark modules on a light background. Inverted or low-contrast colours fail on some phones.
- Keep a clear margin (the "quiet zone") around the code — our downloads include one.
- Print at least 2 × 2 cm for close scanning; scale up roughly 1 cm for every 10 cm of scanning distance.
- Shorter content makes a simpler, more robust code.
- Always test a printed proof with more than one phone before a large print run.
Sharing your Wi-Fi with a QR code
Choose the Wi-Fi type, enter your network name exactly as it appears (it's case-sensitive), pick the security type and enter the password. Most modern iPhone and Android cameras will offer to join the network when scanned.
Using QR codes on business cards
A contact card (vCard) code saves your details directly to someone's phone. Keep it to the essentials — name, phone, email, website — so the code stays small enough to print clearly.
