Below is taken from the Github page.

You can get the app on Android from Google Play or Github Releases.

QR-to-QR logo

This novelty app enables a pair of phones (that have front facing cameras), to share text using QR codes.

Phones facing eachother, to communicate via QRs.

The gist:

  • Put phone A into send mode.
  • Put phone B into receive mode.
  • Put the two phones face to face (experiment with the distance).
  • You should see the QRs change, and the text gradually appearing on phone B.

(Note… it’s not that fast.)

Video demo:

Still from demo video: two phones facing eachother with QR codes showing.
