Im trying to implement card.io feature for my Android application. I have tried sample application given here. I have tried with many cards but of no use. I wonder if its the issue with SDK. Is there any alternative way to do the same.
Indeed, card.io currently cannot scan non-embossed cards. This is a limitation that the developer aware of, check this issue raised in card.io github page.and go through this link also.
hope it answers your question
