How TCGems works
You point your iPhone at a card. TCGems tells you which card it is, down to the printing, and what it sells for.
1. Scan
Open the scanner and hold a card in the frame. With Auto on, TCGems scans as soon as the card is steady, so you can flip through a stack without tapping. Sleeved cards work; very shiny toploaders can catch glare, so tilt them a little.

2. The exact printing
A card's art is often printed many times: in different sets, in different finishes and in different languages. TCGems reads the card number, set and finish, so you get the printing you are holding, not just a card with the same picture. If the match is wrong, tap the card and pick the right one.

3. Today's price
Each printing shows its raw (ungraded) market price from TCGplayer in US dollars and from Cardmarket in euros, refreshed every day, with the price history behind it.

4. Keep it
Add cards to your collection, to lists you name yourself, or to your wishlist. Set pages show how far along you are and which cards you are still missing. Your collection's total value updates with the prices.
