I know I'm late to the party here, but this feed got me thinking about my GTD next actions grocery list. Like others in the thread, I don't see any use for barcodes. But QR codes, on the other hand, can contain very useful information and can be read by just about any smartphone.
I've used Nirvana for GTD for 8 years now and haven't looked back. I use the app on my iPhone and the website on my desktop PC. I thought I'd try a quick experiment using QR codes.
- I used https://goqr.me/ to make a text based QR code. For instance, I entered the text, "Purchase More Tide Laundry Detergent".
- I printed out the QR code, cut it out, and taped it near my washing machine.
- I then used Apple's Shortcuts app on my iPhone to create a script that opens the camera to scan the QR code and copies the text to the clipboard. It then immediately opens my Nirvana app. (Unfortunately, the Nirvana app doesn't have any integrated shortcuts yet)
- I placed a home screen shortcut to the Shortcuts script I created right next to the Nirvana shortcut.
- I ran the Shortcut script and scanned the QR code. It opened the Nirvana app where I click on the inbox.
- I then create the next action by quickly pasting the text into entry field and tagging it using my "grocery" context
This was a much quicker way to to add it to my next actions list than manually typing it in. It could most definitely be improved on, but the concept is there and it works. Now I just need to play around with it some more. Thanks for giving me the idea!
