To begin the trick, you click on “Launch Trick” button. Once the camera view is visible you lock your smartphone and place it on the table. The spectator picks any card then you put all the playing cards back into the box. You unlock the smartphone then you ask the spectator what is the selected card. You press your finger on the screen to select the value you want and you remove your finger from the screen at the position of the suit you want. Once the card has been set into the app, a fingerprint button appears to display a magical beam. You place the deck box on the table or grab it in your other hand. After 5 seconds, the beam reveals the playing card on the box with a burning effect. To exit from the magic trick, you do a long press on the screen.
