FAQ & Use Guide
TLDR - Getting Started
- Remove and position the phone stand position to best center your phones camera over the card.
- Use the Manabox app, have sounds turned on, and the quick scan setting turned on
- To scan in sleeved cards, remove the insert from the inside of the base, leave it in to scan un-sleeved cards
- Sleeved card scanning requires patience and experimentation with lighting, but when setup works great.

Tips: What app is used?

For MTG, Manabox! This is an android, and iOS native app, it has settings to auto add cards that are scanned, and make sounds, tally costs, etc. It’s awesome, and has the best card recognition success rate of any I have tested. Basic settings, Sound on! and you must have quick mode on to scan continuously. If you dont like a result for either misidentified foil or set, tap those indicators of "normal" or set icon to change those details. For bulk foil scanning, I like use the “prefer foil” checkbox to scan foils separately from std non foil cards. Here is very helpful mana box getting started guide → Once you have scanned in your cards, you can edit any details you may want to change, and then save the scanned card list to your collection, or decks, and from there export as .csv or text for sites like moxfield and archidekt.
Delver lens for MTG and Pokemon also works great with many camera control options that are not present in ManaBox
There are tons of other apps to use, try them all, see what works for you, people like TCG app, we have had mixed results, good with MTG, Bad with Pokemon more, let me know if you would like a specific guide for any of these! Collectr does NOT work with the Card Slinger.
Tips: Scanning Sleeved Cards
First, remove the tray insert if you have one, this will allow a nice fitment for sleeved cards, re insert this to scan in un-sleeved cards.
Scanning sleeved cards can produce mixed results depending on scanning application in use, sleeve type and lighting. Its best to experiment with light and what space you are in for best results. The best results will be obtained from using an indirect, generous soft light source that does not produce harsh shadows, but try different environments to get best results. The lite version of card slinger only supports un-sleeved scanning.
Tips: Lighting
When scanning un-sleeved cards, lighting is very very forgiving ( depending on model of camera in use, and app of course ) for sleeved cards the best results will be obtained from using an indirect, generous soft light source that does not produce harsh shadows at angles, but try different environments to get best results, patience and experimentation will yield near perfect results.
Does Scanning Cards Damage Them?
Does it damage the backs of cards?
No, not that I can tell, I have scanned in thousands of cards with my pre production units, and I can't find any damage
Does it damage the corners of cards?
Again, as above, no! Not that I can see from scanning thousands of cards, but if you want to throw them in as hard as you can, anything is possible.
Is it possible to damage cards while scanning using the sling box?
100% it is possible, and it's possible to damage cards using any method if you are rough, but it is fully avoidable. careless or use too much force when handling cards. From what I can tell, this method of using the card slinger does less damage to cards than any mechanical method.
