Frequently asked questions
Do QR codes expire?
No. These are static codes with the data inside, so they never expire and cost nothing. A link stops working only if the destination site goes offline.
How does Wi-Fi QR work?
Enter network name, password and security type. Guests scan to join without typing. The password is processed only in your browser.
What size should I print?
At least 2×2 cm, dark code on a light background. More data makes denser codes, so print larger and test-scan before printing.
What is error correction?
It lets the code stay readable if partly damaged or covered. Higher levels (Q/H) tolerate more damage but look denser.
