QR-to-QR (android app)
Below is taken from the Github page.
You can get the app on Android from Google Play or Github Releases.
This novelty app enables a pair of phones (that have front facing cameras), to share text using QR codes.
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.)
