How to check a Union Arena card’s value with your iPhone
-
Step 1
Pick Union Arena and point the camera
Choose Union Arena in the game menu at the top of the scanner and hold the card flat inside the frame.
-
Step 2
TCG Vault reads the card
On-device text recognition reads the card’s printed text, including the number along the bottom-left edge (such as UE03BT/JJK-1-040), and TCG Vault matches the artwork to pick the version.
-
Step 3
See the price, save the card
The market price, refreshed daily and shown in your own currency, appears with the card. Add it to a collection and the collection’s total value updates.
On each card you see its name, set, collector number, rarity and market price. Premium adds 1-, 3- and 6-month price history, more than one collection and a direct link to the card on the marketplace. Auto mode keeps scanning as you swap cards and flags duplicates, which helps with a stack of new pulls.
What to check on a Union Arena card
-
01
Read the number left to right
UE03BT/JJK-1-040 is the product (UE03BT, a booster), the series (JJK, Jujutsu Kaisen), the series volume (1) and the card (040). UE means an English card; UA marks Japanese ones.
-
02
Stars mark the parallels
The rarity pill shows the version: SR, SR★, SR★★ or SR★★★. The star versions keep the base card’s number, and SR★★★ cards are the most valuable Union Arena cards, so count the stars before you save.
-
03
One card can sit in several products
Starter decks share booster numbering, and promos reprint cards under UEPR codes, sometimes in a higher rarity. TCG Vault lists each product’s version with its own price.
-
04
AP cards and promos are in the catalog
Action point cards and event promos are listed with the English-language Union Arena cards sold on TCGplayer.
