## What it is
card.io is an Android SDK that provides fast credit card scanning using the device camera, with OCR-based number recognition and a manual entry fallback. It integrates into Android apps via a simple activity intent and was distributed through Maven Central.

## Use cases
- scan credit cards in a mobile app
- extract card numbers from camera images
- add payment card entry to an android checkout flow
- replace manual card number typing with camera scanning
- read card expiry and cvv during onboarding

## When to choose
- building an Android app that needs quick credit card capture via camera
- you want a drop-in scanning activity with manual fallback

## When to avoid
- you need iOS or cross-platform support from this repo specifically
- you need actively maintained software - last release was 2017 and the service has been retired
- your app must run on devices without a rear-facing camera
