Scan cards at a busy table
Checked

Scanning is fastest when you treat it as a starting point. The camera can read a card quickly, but you are still the one who checks it is the right card.
Read the card on the device
Holo Folder recognises text on the card on your device. Hold the card flat, avoid glare from overhead lights and let the camera settle before you move on.
Confirm ambiguous matches
Reprints, promos and different finishes can look alike. When a match is ambiguous, the app asks you to confirm it. Take the extra second. The wrong printing leads to the wrong price.
Fall back to search
If the camera is unavailable or the card is in a toploader that reflects light, search by name, set or number instead. It is often just as quick for one card.
