Cardlens: Card Scanner for iPhone

Questions, problems, or a card that scanned wrong? We read everything. Email support@keystonecards.com and we'll get back to you quickly.

Scanning tips

• Fill the guide. Line the card up inside the on-screen frame and hold the phone steady, 8–12 inches away.
• Mind the glare. For graded slabs and holos, tilt slightly so overhead light isn't reflecting off the plastic.
• Rescan freely. A fresh scan of the same card replaces the earlier read — the newest scan wins.
• Check the Review queue. When Cardlens isn't sure, the scan is flagged for a quick one-tap confirm or fix.

About prices

Prices are estimated market values from recent sales data, updated continuously. Graded cards show the value for the exact grade on the slab. Estimates are informational only — they aren't appraisals or offers to buy or sell.

Privacy

Card recognition runs entirely on your device — camera images are never uploaded. Details in our Privacy Policy and Terms of Use.
