Hamelin Card Fishing

CardFiching.

Effect:
The magician gives a card to choose; which must be memorized or remembered by the viewer and/or the audience. The magician then asks the spectator to insert the card into the deck and shuffle to prevent the magician from knowing its location or value.
The magician leaves the deck on the table... It shows a cell phone where a hook can be seen at the top of the screen. Place the cell phone on the table in front of the deck of cards so that the bottom side of the screen is attached to the top side of the deck of cards.
Tap on the device's screen in the center of the hook to activate it... and that's it.... The card chosen by the spectator becomes visible on the screen strung on the hook that I visibly lower to look for the card and shows it on the screen.
But it is not all the magician touches the hook or hook and returns the card to the deck of cards, but by rotating it or turning it over in such a way that it will be contrary to all the others, the magician or someone in the audience scatters the cards on the table and confirms that the chosen card is turned upside down.
Note: You must be able to force a card and control it.
