If you are unable to scan your cards, see if you are taking photos in any of the following environments.
Optimal brightness to read cards
When it is too bright or too dark, it may take time to scan the card.
We recommend a brightness where you can see the letters on the cards.
Optimal background colors to read cards
If the card and the background are the same color, it may take more time or fail to scan the cards.
We suggest scanning cards with a different colored background.
