01 What should I look for in a Yu-Gi-Oh! card scanner app? The best scanner should identify the exact printing, keep the scan history searchable, show current prices, and add a result directly to a collection or deck. YuScan combines those steps in one iPhone workflow and performs card recognition on the device. 02 How do I scan a Yu-Gi-Oh! card with my phone? Open the YuScan scanner, place one card inside the camera area, and keep the artwork visible until the match appears. You can use the flashlight in low light and change camera lenses without leaving the scanner. 03 Can YuScan identify the set, rarity, and printing? YuScan matches a scan against individual card printings rather than returning only a card name. The result includes the expansion, set code, rarity, edition, available variants, and printing-specific market prices. 04 Does the Yu-Gi-Oh! card scanner work offline? Yes. Card recognition and the downloaded card database work on the iPhone after the initial data setup, so scanning does not depend on a live server connection. Internet access is still needed to download database, model, and price updates. 05 How can I track my Yu-Gi-Oh! card collection? Create collections for binders, trade stock, sealed products, or any organization you prefer. Add cards from the scanner, search, set checklists, or multi-select mode, and record quantities for duplicate copies. 06 How do I find the value of my Yu-Gi-Oh! collection? Add the exact printings you own to a YuScan collection and choose the pricing source and currency that match your market. YuScan calculates the collection total from printing-level prices and updates the value when price data changes. 07 Can I build and validate a Yu-Gi-Oh! deck on iPhone? YuScan separates Main, Extra, and Side Deck cards and shows live counts while you build. Add cards from search, a card detail page, or your collection, then review validation warnings for deck size, card placement, and copy limits. 08 How can I search the Yu-Gi-Oh! card database? Search YuScan by card name, then narrow results with filters for language, card type, attribute, rarity, expansion, and other card properties. Results show prices and the number of known printings before you open the full card page.
