A magical, modern and very powerful prediction. All this is what you will find with the QR card.
Imagine having a prediction always in full view. The spectator chooses a card that is then lost in the deck. Now say that the card is trapped in another dimension and turn over the QR card... Scan the QR code and a video will appear on the viewer's mobile phone with the selected card... which soon after will disappear. An arrow will appear pointing to the card on the table. On the table instead of the QR card there will be the card selected at the beginning!
Leave a magical, visual and modern memory in the spectators mind! Immediate repeatable as there is not a single QR code (you can apply it wherever you want !!) so it can be repeated several times!
