What you can do
Trade face to face
Lay a trade out right at the table. Cardinal shows the value on each side, who it favors, and the add-on that evens it up. A fair trade in seconds, no mental math.
Scan to add
Point your camera at a card, even a Japanese one. Cardinal knows what it is and drops it into your binder with its value.
Know what it's worth
Real, current market prices, your whole collection's value at a glance, and graded slab prices from PSA, CGC and BGS. Widgets keep it on your home screen.
Finish your sets
Sort by set, log condition and cost, and watch the completion rings fill in as you close the gaps.
