Ways to use QR codes
- Link QR: connect store menus, business cards, flyers and posters to your homepage or booking page
- Wi-Fi QR: guests just scan with their camera to join Wi-Fi without typing a password
- Text QR: share contact details or short notices
QR codes that never expire
Some QR services route through their own server address, so after a while the QR stops working or asks for payment. This generator puts your address directly into the QR code, so it never expires.
Printing tips
- Print at least 2×2cm.
- The QR and background need strong contrast (dark QR + light background).
- Test-scan with several phones before printing.
FAQ
How many characters can a QR code hold?
Up to several hundred Korean characters, but the longer the content, the denser the QR and the harder it is to scan. Shorter links are better.
