Hi Greg

On the subject of QR Codes, I found a very good pure JavaScript QR Code 
generator library:

https://github.com/zenozeng/node-yaqrcode 
<https://github.com/zenozeng/node-yaqrcode>

I’ve completed the initial work of making it into a TW5 plugin (very 
straightforward as the library is clean and simple), and will publish it 
shortly. Playing with it prompted me to download a QR Code reader app for my 
smartphone, and I’ve found that QR Codes are indeed quite powerful.

The plugin lets you encode any text as a QR Code: not just a URL, but even the 
content of tiddlers can be made into a QR code. So you could transfer a 
shopping list from your laptop to your phone just by snapping it.

results in the image below.

Best wishes

Jeremy.
