WiFi QR Code Sharing Card
Contents
Introduction
Ever since discovering I could create a QR code for easily connecting to Wi-Fi networks I have been making QR codes using QtQR and so on and importing those into a LibreOffice document for printing, sharing and saving. Then more recently I started promoting this blog’s local resource lists using a QR code on a 3x5 index card which is turing out to be a great format for printing and sharing locally.
Idea
Then I had the idea why not make a 3 X 5 size card form that is the page so you could fill in the information and then just Print it right from the web page. And avoid a lot of the manual work of generating documents and QR codes separately.
Solution
I shared that with Microsoft Copilot, and it helped me come up with the following solution in seconds. I needed to make a few minor formatting changes and correct one mistake where it was passing a string of None instead of `` for the None encryption option, but otherwise pretty much as is solution.
How to use
- Press the link below in “Live Example” section.
- Type in the WiFi network
Name: - Type in the WiFi network
Password: - Press the Print button on the ‘Wifi QR Code Sharing Card Generator’ webpage in the lower right corner.
- Adjust Paper size to 3" X 5" (US inches) for a standard 3X5 index card.
- Load a 3x5 index card into your printer as directed by the printer manufacture.
- Click Print on your devices printer dialog, dropdown, window, box or etc.
- Keep your printer card handy and scan the QR code on your printed card with devices you want to connect to your Wi-Fi network.
