card.io provides a SDK for mobile developers to easily accept credit cards in their mobile apps. Typing on mobile phones is slow, and most consumers don't have a separate hardware attachment to swipe a credit card. card.io solves both of these problems: customers just hold a credit card up to the phone, and card.io reads the card information using the phone's camera.
This app is a demonstration of the card.io SDK. It does not process payments, and card.io never saves card information.
