Camera issues, wrong matches, and scan limits explained
The Misprint card scanner works for both PSA graded slabs and raw (ungraded) singles. Most scanning problems come down to camera permissions, lighting, or trying to capture too much at once. This guide walks through the fixes for the issues we hear about most, plus what to include when you report a scanner bug.
The scanner needs access to your phone's camera. If you tapped "Don't Allow" the first time, or you're on a fresh install, the camera view stays blank. Grant the permission in your phone settings:
After enabling the permission, fully close and reopen the app so the scanner can pick it up.
Identifying a card happens on our servers, so the scanner needs a working connection. If a scan spins or fails, check that you're on stable Wi-Fi or cellular data, then close the scanner and reopen it. If it keeps happening, make sure you're running the latest version of the app (see below) and restart your phone. A failed scan does not count against your daily limit, so it's safe to retry.
Recognition is very accurate, but look-alike cards, reprints, and unusual variants can occasionally produce the wrong match. If the scanner returns a card that isn't what you scanned, the best thing you can do is report it as a catalog issue so we can correct the mapping for everyone.
When reporting, include the PSA cert number (for graded slabs) and a screenshot of the incorrect match. See our guide to reporting a catalog issue for exactly what to send and where.
For graded slabs, the scanner reads the label and barcode on the PSA case. If it can't lock on, adjust how you're holding the slab:
Image quality is the single biggest factor in a good scan. A few simple habits solve most problems:
The scanner is built to identify one card per capture. If you fit multiple slabs or singles into a single frame, it can't tell which one you mean and may match the wrong card. Scan one card at a time. To scan a stack quickly, keep capturing cards one after another and they'll be grouped together in your results.
Raw singles rely entirely on the card artwork and text, so framing matters even more than with slabs:
There is a daily scan limit shared across PSA slabs and raw singles combined, and it resets each day. Subscribers get a higher daily limit than free accounts.
Only successful scans count. A scan uses up a slot only when it produces a confirmed card match. If a scan fails to match anything, it does not count toward your daily limit, so retrying a tricky card never costs you a slot.
Many scanner problems are fixed in newer releases. Before troubleshooting further, update the Misprint app to the latest version from the App Store or Google Play, then fully close and reopen it. Running an older version can cause the scanner to behave unexpectedly even when everything else is set up correctly.
