How scanning Union Arena cards works

Four things happen between raising the camera and seeing a price, and all four of them happen on the phone.

Step 1
Point the camera at a Union Arena card
A detector running on your iPhone finds the card in the frame — sleeved, in a binder pocket, or held at an angle. Nothing to line up, nothing to type.
Step 2
The artwork becomes a fingerprint
An on-device model turns the illustration into a numeric fingerprint. It reads the picture rather than the text, so foil stamping, glare on the title or a worn edge does not matter.
Step 3
Every Union Arena card, matched offline
The Union Arena database downloads once and lives on your phone, so the match comes back in about a second with no connection at all — the state you are usually in at a card shop.
Step 4
Name, set and price, together
You get the card name, its set, collector number and rarity alongside the latest USD market price. Keep it and it joins your collection, with a running total of what the lot is worth.

What Union Arena scanning is like

Union Arena spans a lot of licences, and its cards come straight from anime key art — visually distinctive, which is ideal for artwork matching even when you have four different series sitting in the same stack.

Union Arena crossover singles across every licence, with market prices that update daily.
