Static QR codes that never expire
Many “free” QR sites make a dynamic code that points to their own short link, then stop it working when a trial ends. The codes made here are static: the link, Wi-Fi details or text are written straight into the pattern. They work for ever, there is nobody in between, and no scan is tracked.
What each type does
- Website link: opens the page. Use the full address starting with https://.
- Wi-Fi: phones join the network without typing the password – handy for guests, cafés and holiday lets.
- WhatsApp: opens a chat with your number, optionally with a message already typed.
- Email, phone, SMS: start a message or a call.
Printing tips
- Choose High error correction for print – the code still scans if part is scratched or covered.
- Keep at least 2 cm across for close-up scanning, larger for posters (roughly 1 cm per 10 cm of scanning distance).
- Use a dark colour on a light background; leave the white border (the “quiet zone”) around it.
- Download SVG for print – it stays sharp at any size. Always test-scan before printing many copies.
Worked example: a Wi-Fi code for a network called “CafeGuest” with WPA password “coffee2026” holds the text WIFI:T:WPA;S:CafeGuest;P:coffee2026;;. Scanning it with a phone camera offers to join the network.
Privacy
Your Wi-Fi password and other details stay on your device; the code is drawn in your browser.
Ideas for using QR codes
- Shops and cafés: a code on the counter that opens your menu, WhatsApp or Google review page.
- Events: a code on a poster that opens the booking page.
- Home: a Wi-Fi code on the fridge so guests can join without asking for the password.
- Business cards: a code that opens your website or saves your number.
