An iOS SDK for fast, easy credit card scanning in mobile apps using the device's camera.
card.io is an iOS SDK that enables mobile apps to scan credit cards using the device's camera. It captures card numbers, expiry dates, and CVV codes quickly, reducing manual entry errors and streamlining checkout processes. Originally developed by PayPal, it is now open-source and widely used for payment integrations.
iOS developers building e-commerce, payment, or financial apps that require secure and efficient credit card input. It's ideal for teams looking to enhance user experience in mobile checkout flows.
Developers choose card.io for its reliable, camera-based scanning that works offline, its flexible integration options (view controller or custom view), and its open-source nature, which allows customization and transparency compared to proprietary alternatives.

Uses the device's camera to quickly capture card numbers, expiry dates, and CVV codes, reducing manual entry errors as highlighted in the README's key features.
Can be integrated as a full CardIOPaymentViewController for quick setup or as a customizable CardIOView for more control, per the sample code in the README.
Includes support for manual card entry when scanning is unavailable or fails, ensuring a seamless user experience during checkout.
Automatically blurs screenshots in the payment view controller to protect sensitive data, a security feature mentioned in the README.
Optional preloading of resources reduces initial scan delay, improving performance as noted in the hints and tips section.
Manual integration without CocoaPods requires adding multiple frameworks and adjusting linker flags, which can be error-prone and time-consuming, as detailed in the setup instructions.
The SDK is exclusive to iOS, forcing developers to find separate solutions for Android or web platforms, limiting cross-platform app development.
Includes libraries like OpenCV and several frameworks, increasing the app's binary size and potentially affecting performance for lightweight applications.
Open-sourced in 2014, the project may lack regular updates, risking compatibility issues with newer iOS versions and missing modern features.
