The chain for every card.

Card Shop by Twomiah is the modern home for trading card collectors and breakers — a single app for scanning, trading, showcasing, and protecting your collection.

WHAT YOU CAN DO

• Scan and verify cards. Tag any card with a Card Shop QR sticker and you'll have permanent, verifiable ownership records — even at trade shows.

• Trade locally and online. List cards on the trade board, send offers, and message other collectors. Accept, counter, or decline — all in-app.

• Build showcase binders. Curate themed collections, share them publicly, and get views, offers, and conversion stats on every binder.

• Track market value. See blended values, sold-history trends, and liquidity signals from PSA, CardLadder, and live marketplace data.

• Get deal alerts. Set up Deal Radar on cards from your wantlist and we'll ping you the moment one drops below market.

• Protect ownership. Every card scan, transfer, and reprint is logged in a chain-of-custody audit trail you can show to a buyer or insurer.
