Oh, No Reason…

I’m not sure why I did this exactly, but the other day I decided to download a QR code generator onto my phone. I have no real need, but it looked like a fun thing to play with, so I made a few codes (my contact info, “Hello World!” etc), then I thought it would be pretty cool to read and write them from the laptop, so I downloaded a program called qrencode to write them, and one called zbar to read them, and I had a bunch of geeky fun using all my new toys.

Then I got the idea: what if I could take a picture of a QR code, with datestamp and GPS metadata added? I could then extract the QR data, and the time and place it was gathered, like maybe something an inventory program would use. I downloaded another program called exiftools, and found how to get the date/time and location from the photos, but the final step, extracting the QR data from the photo of the QR code image, was a failure. I have no idea why yet.
