I-nigma provides a service for creating QR codes. For example, the following QR code contains my contact information.
I-nigma’s form-based service creates
<img> codes for embedding on web pages and is much easier to use than Google’s undocumented service.
Update: Reader Dean Collins expresses some concern about I-nigma’s methodology. Follow the discussion in the comments to a prior post.
The Google Chart API now generates QR Codes.
For example, the following URL results in the QR Code for https://brentlogan.com/.
Note, the above list URL is shown on two lines for space reasons only. It should be one continuous URL with no spaces.
<img> form to embed the resulting QR Code in a web page does not (yet?) work. I guess that’s to be expected when using an undocumented feature of the API.
Update: The following now works:
<img src="https://chart.googleapis.com/chart?chs=100x100&cht=qr&chl=https://brentlogan.com/" />
resulting in the image below:
