The Collection Search mode allows you to search your collection for a card by scanning it. This is useful for checking if you have already added a card into your collection or finding where similar cards are located.
To access Collection Search mode, swipe left while in the main camera view so that the Magnifying Glass symbol is highlighted (pictured below).
Once a card has been recognised, the number of copies in your collection will be displayed next to the card's name at the top of the screen.
To display the cards that match, tap the Magnifying Glass button (pictured below). This will open your collection with a search for the card's name automatically entered.
