Scanning singles without tapping anything: point the camera, it identifies and moves on
Most card scanners make you take a photo and wait. I wanted it to feel like a barcode gun: hold the camera over a card, it locks on, you move to the next one. No shutter, no confirm tap.
It runs about a second per card. The clip is real time, not sped up.
Three things that took the longest to get right, and are the reason it isn't just "take a photo and hope":
It doesn't need the card centered. It searches across a range of positions and scales every frame, so a card sitting off to the side or slightly rotated still locks. This was the single biggest source of failures early on - people naturally hold a card wherever it lands in frame, not neatly inside a guide box.
Foils don't break it. Holo and secret rares throw off image matching badly because the shimmer changes with every angle in most apps. Took a lot of iteration to get those matching as reliably as flat cards.
It tells you which printing. Base vs alt art is the part most tools get wrong, and it's the part that matters if you're cataloging properly. Same card number, different card.
Covers Masters through BT31 and Fusion World through FB10, alt arts and promos included. Free, no ads.
It's a one-person project, and it's still rough in places. If it misidentifies a card, I'd honestly like to know which one - that's the fastest way it gets better.
