Improve scan accuracy

Photo quality basics

• Use clear, well-lit photos — minimal glare gives the best results, especially on chrome and foil cards.
• Shoot on a plain, solid background.
• Keep the full card (or slab) square and inside the frame.
• Capture serial numbers and cert numbers clearly so CardSense can read them.
• Retake any photo where the text is blurry.
• Supported image formats are JPG, PNG, and WebP.

Always capture both sides

CardSense reads the front and the back together. Capturing both sides is the single biggest accuracy win — dual-side processing pushes field extraction to about 70%+, because the back carries the card number, set, copyright year, and parallel details the front often hides.

You can still scan a card with only one photo when that's all you have. CardZen tells you first that a one-sided scan reads fewer fields and costs the same scan as a two-sided one, so the trade-off is yours to make before the credit is spent — and it flags the card afterwards so you know which ones were read from a single side.

When CardSense misses something

Fix the field during batch review. CardZen keeps your confirmed edit and uses it as the trusted record from then on, so the same card won't need correcting again.

Accurate fields mean more comps

Comp matching leans on player, year, set, card number, and parallel. The more of those are right, the more sold and active comps CardZen can match to the card.

Common misspellings in a parallel are snapped to the real name automatically — Refactor is matched as Refractor — and a card whose strict match finds nothing keeps the comps it already had instead of dropping to zero.

Keep an eye on your scan allowance

Each card you capture uses one scan from your monthly allowance, shown in the top bar (for example "859 / 1,000 scans"). The count resets at the start of each billing month.

If you're running low, upgrade your plan from Settings to raise the limit. Better photos help too — fewer retakes means fewer scans spent.
