CardBook is a YuGiOh singles marketplace with powerful card detection scanning, handy collection management tools, and an easy buy/sell process.

Buy/Sell on CardBook!
Add and search for cards to buy and sell. Put a card up for sale by scanning it and adding it to your inventory. A cropped picture created from the scan will be waiting in your inventory, ready to be priced and listed. Receive a text when a card is purchased, and if you are a seller, a ready-to-print shipping label will be sent to your phone. You can manage your inventory, and monitor the status of purchases in the Inventory view.

Sell a card by scanning!
While scanning a card, tap to add it to your inventory where its image will be stored and auto-cropped, ready to list on the market.

Scan one card or more! 
CardBook supports active card tracking for single or multi-card modes. (see how many you can scan at once!)

Save and create decks!
Did you want to save a card you just scanned? Do you need to make a decklist? Or do you just want a place to store some group of cards? While scanning, open up the card detail view and add that card to any decks you've made. You can also simply search for any card in our database while inside a deck.
