+# 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](https://github.com/stripe/stripe-android/tree/master/stripecardscan) 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.
+
+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](https://github.com/stripe/stripe-android/issues) and [iOS](https://github.com/stripe/stripe-ios/issues). For billing support, please email [[email protected]](mailto:[email protected]).
+
+For the new product, please visit the [stripe github repository](https://github.com/stripe/stripe-android/tree/master/stripecardscan).
