Question 1

How do I create a WiFi QR code for my restaurant or cafe?

Accepted Answer

Enter your network name (SSID), password, and encryption type (WPA/WPA2/WPA3) into a WiFi QR code generator. The tool encodes this information into a standard QR image. Print it on table tents, wall signs, or menu cards. When customers scan with their phone camera, they connect automatically — no typing required. OwnQR generates WiFi QR codes for free with no account needed.

Question 2

Is it safe to share WiFi through a QR code?

Accepted Answer

Yes. A WiFi QR code only contains your network name (SSID) and password in a machine-readable format — the same information you would give verbally. It does not grant admin access to your router or expose other devices on the network. For best security, use a dedicated guest network with WPA2 or WPA3 encryption, and regenerate the QR code whenever you change the password.

Question 3

What is the best size for a WiFi QR code on a table tent or poster?

Accepted Answer

For table tents scanned from 1-2 feet away, print at least 2×2 cm (0.8×0.8 inches). For wall posters scanned from 3-6 feet, use at least 8×8 cm (3×3 inches). The general formula is: minimum QR size = scanning distance ÷ 10. Always download in SVG format for print to ensure the code stays sharp at any scale.

Question 4

Do WiFi QR codes work on both iPhone and Android?

Accepted Answer

Yes. iPhones running iOS 11 or later and Android phones running Android 10 or later can scan WiFi QR codes directly with the built-in camera app. The phone detects the WiFi credentials and shows a 'Join Network' prompt — no third-party scanner app is needed. This covers over 95% of smartphones in use today.

Question 5

What happens if I change my WiFi password?

Accepted Answer

You will need to generate and print a new QR code, because the password is encoded directly in the QR image. This takes about 30 seconds on OwnQR — the generator is free with unlimited uses. Tip: if you change passwords frequently, consider a dynamic QR code ($15 one-time) so you can update the linked password page without reprinting.
