One picture for the eye.Another for the camera.
Upload a picture people will see on a wall, a page or a screen, and a second picture hidden behind it. Anyone who opens your scan link and points a phone camera at the first picture sees the second one appear on top of it. No printed code, no app to install.
- Upload two pictures. The one everyone sees, and the one only the camera shows.
- Print or display the first picture. It stays an ordinary picture with nothing added to it.
- Share the scan link. People open it, allow the camera, and point it at the picture.
