Card.io Does not scan non - Raised Digit Credit Cards

I have a problem with scanning non-raised digit credit cards with card.io sdk. I haven't seen any explanation about this issue on the official site of card.io. Does this sdk work for only raised digit credit cards?

Why does my credit card not scan?

The magnetic strip is scratched This is likely the most common physical reason for a credit card to stop working. If the magnetic strip gets roughed up enough it may eventually become unreadable. Be gentle with your plastic and try to keep your cards together in a wallet or money clip.

Jeff here from card.io. In short, yes, the sdk only works for raised digit credit cards. Scanning cards on a mobile device is hard, and the team chose to start by scanning the largest percentage of cards on the market, and do it well. There are plans to support more cards and card types in the future. For now, please know that the sdk doesn't scan everything. Hope that helps!
