## What it is
card.io is an iOS SDK that provides fast, easy credit card number scanning using the device camera in mobile apps. It ships as a static library with headers, integrable via CocoaPods, and is backed by PayPal.

## Use cases
- scan credit cards with camera in ios app
- add card scanning to mobile checkout
- ocr credit card numbers from camera
- reduce manual card entry in payment flow
- integrate card.io sdk via cocoapods

## When to choose
- building an older iOS app (iOS 6.1+) that needs camera-based credit card scanning
- you want a drop-in static library with sample apps for quick integration

## When to avoid
- starting a new project - the SDK is unmaintained with no releases since 2018 and card.io services have been sunset
- you need Android or cross-platform support from the same actively maintained codebase
- your app targets modern iOS versions or 64-bit-only requirements beyond the SDK's tested range
