How Prismint checks your Pokemon cards
Prismint turns a photo of your Pokemon card into a price, a condition estimate, and authenticity risk signals. Built for collectors, players, and resellers who want quick answers before buying, selling, or trading.
Step 1 — Scan
Open the app and point your camera at the front of any Pokemon card. Prismint frames the card automatically and captures a sharp, well-lit image. For a basic scan, the front is enough — you get card recognition and a market price within seconds. Want authenticity or condition signals too? Add a photo of the back. The back image lets Prismint check copyright text, logo placement, and card wear that only shows on the reverse side. Both photos stay on your account so you can review them later.
Step 2 — Price
Once Prismint recognizes your card, it pulls the latest market prices from both US and European sources. Prices sync daily, so you see what the card sells for right now — not last month. You get a low price, an average market price, and the last recorded sale where available. Prices display in USD and EUR depending on the source. If the card has multiple variants (holo, reverse holo, promo), Prismint matches the specific variant you scanned so the price is accurate to your copy.
Step 3 — Risk signals
Prismint runs your card through 12 pattern-based checks on the front and a separate back-of-card validation. It looks at print quality, color consistency, text alignment, copyright year, and logo placement. The result is a risk level — low, medium, or high — with specific reasons for each signal. This is not a verdict. No scanner can guarantee a card is legitimate or not. Prismint gives you the signals so you can make a better decision. If you answer optional follow-up questions about the card (texture, weight, light test), the risk score refines further.
Step 4 — Condition
Prismint measures three physical properties from your scan: centering (how evenly the border surrounds the artwork), corners (sharpness vs. whitening), and edges (clean cuts vs. nicks or peeling). Each gets a score, and together they produce a condition estimate: Near Mint (NM), Lightly Played (LP), Moderately Played (MP), or Heavily Played (HP). This is an estimate, not a grade. Professional grading services examine cards in person under controlled conditions. Prismint gives you a fast read so you know what to expect before submitting for grading or listing for sale.
Under the hood
We combine fast card recognition with rule-based authenticity signals and classical computer vision for condition — all in seconds, with clear, honest results.
Card recognition
Local OCR first for speed. Full and premium scans use cloud-based text detection for stronger results, then match against our catalog with a numeric confidence score. Low confidence surfaces a warning instead of a guess.
Authenticity check
A scope-based counterfeit pattern matcher plus a back-of-card validator that reads copyright year and logo cues. A weighted questionnaire can refine the score. You get a risk level with plain-language reasons — never a hard verdict.
Condition check
Frame detection, luminance profiling for centering, HSV sampling for corner and edge wear. Surface analysis is intentionally conservative. You get an estimated condition band — we never guarantee PSA or BGS grades.
Results are signals to help you decide, not guarantees of authenticity or grade.
