Deprecation Notice

Hello from the Stripe (formerly Bouncer) team!

We're excited to provide an update on the state and future of the Card Scan OCR product! As we continue to build into Stripe's ecosystem, we'll be supporting the mission to continuously improve the end customer experience in many of Stripe's core checkout products.

This SDK has been migrated to Stripe and is now free for use under the MIT license!

If you are not currently a Stripe user, and interested in learning more about improving checkout experience through Stripe, please let us know and we can connect you with the team.

If you are not currently a Stripe user, and want to continue using the existing SDK, you can do so free of charge. Starting January 1, 2022, we will no longer be charging for use of the existing Bouncer Card Scan OCR SDK. For product support on Android and iOS. For billing support, please email bouncer-support@stripe.com.

For the new product, please visit the stripe github repository.

Overview

This repository contains the legacy, deprecated open source code for Bouncer products (e.g. CardScan). See the individual sub modules for more information on each.

CardScan is a relatively small library that provides fast and accurate payment card scanning.

CardScan is the foundation for CardVerify enterprise libraries, which validate the authenticity of payment cards as they are scanned.
