CardSignal turns your trading card collection into a data-driven investment portfolio. Stop guessing what your cards are worth, start knowing when to act.
MARKET SIGNALS
Every card in our database is scored on real market momentum, not just price. CardSignal tells you whether to BUY, HOLD, or SELL - before the market moves. Backed by daily pricing data across thousands of cards and hundreds of sets.
Launching with full Pokemon TCG coverage. Additional trading card games coming soon.
INSTANT CAMERA SCAN
Point your camera at any card. CardSignal reads the set number, identifies the card, and pulls live pricing in seconds. Add it to your portfolio with one tap.
REAL PORTFOLIO P&L
Track exactly what your collection is worth today — and how it compares to what you paid. See gains and losses across your sealed products and singles with 30, 90, and 180-day performance windows.
SEALED PRODUCT RANKINGS
Booster boxes, Elite Trainer Boxes, and sealed products ranked by investment momentum. See which products are trending up before everyone else figures it out.
PORTFOLIO HEALTH SCORE
Get a graded report on your collection's investment quality. CardSignal identifies which cards to cut, which to hold, and where your real upside is.
VENDOR OFFER CALCULATOR
The Vendor page allows users to asses entire collections of sealed products and cards at the same time. Furthermore, CardSignal will suggest a fair offer percentage that is weighted based on the fair offer percentage of each product in the collection. No more guessing on what is fair for the collection when some items should be purchased at 90% vs 70%. When added to inventory the weighted average you paid will be displayed in the cost section to see live price of value vs what was paid. A HUGE step for easy vending and decision making!
