Jogar uma partida fria sobre seus amigos e familiares;)
Prank your friends and family, by making them believe that this application can detect their names, by scanning their faces only.
All that you have to do is to type a name, and press the ready. Then you will have to take a picture of them.
The application will simulate a photo scanning process, and when it's done, the name you typed will be revealed.
Try not to make it suspicious, and hopefully you will manage to prank them!
