This is a remix of the WiFi QR Code Sign - Embedded Magnet Version that uses embedded 8 mm x 3 mm magnets (Amazon) and has a recess for a 25mm NFC sticker (Amazon).
Use this sign to share your Wi-Fi SSID and password with your guests. Most mobile phones are capable of interpreting the QR code and will connect to the Wi-Fi network without manually select the SSID and enter the password.
Note: Your Wi-Fi SSID and passcode are available to anyone who has the QR code. Especially you shouldn't share unedited makes of this sign 😃
Since this should have a QR code with your Wi-Fi SSID and password, you have to make your own for this to be useful! But it is quite straight forward:
You can write the NFC code using the NFC Tools App.
With the tag flashed, you can stick it on the backside of your Wi-Fi QR-code sign. Your guests can now can or use NFC to connect to your Wi-Fi 🎉.
