Just the other weekend, I had to exchange contact details using quite primitive means with a fantastic new friend after a deeply enjoyable hike up Table Mountain via the India Venster route.

We could not get the flashy new iPhone-bump method to work. Although the animation triggered with each bump, no contact details were exchanged, a failure which caused the Android user at the table much mirth.

That incident drove me to retrieve some old Python code I had written to try out Segno, a QRCode generator library for Python, and to test out the recently announced WASM capability of the new Marimo reactive Python notebook.

In the next section I’ve embedded the WASM-powered notebook in question. Type in your details, click on submit, download your QRCode which should work for both Android and iPhone.
