QuickeR: Using video QR codes to transfer data
The basic idea is to transfer data between 'devices' using 'video' QR codes, i.e. by splitting the data over multiple QR codes, which are then presented one after another as a video. Another device can then capture this video, split it into the separate QR codes, process them and recombine their contents to reproduce the original data.
In this example, I've taken four QR codes, each saying respectively:
1This
2is
3a
4test
And combined them into an animated gif. You can then see the Android app I created that captures the video and recombines the data into a single String: 'Thisisatest'.
Note: the number is there to denote the order. As it was just a hack, I did that very simply, but I'm planning to use some much more advanced schemes & encodings in the near future.
