Online access and offline downloads
Supported paper can be used while connected to the internet. Paid members may also download the libraries they need before a game. Large libraries remain separate so you control how much space is used on each phone, tablet, or computer.
Paper support can vary by style
A brand may produce several paper families with different numbering systems. Always choose the exact option shown on your paper. If a printed number is outside the available range, Card Watcher will tell you instead of displaying an unrelated card.
