Abstract: A high security communication channel between the back-end application and the customer's mobile device is disclosed. An application programming interface that integrates into a service provider's back end application and a software development kit that integrates into a mobile application on the customer's mobile device establish a two-way communication channel between the back-end application and the mobile device. When a customer is ready to complete a transaction in one of the service provider's sales channels, such as online, by phone, in-person, by mobile device, or at a kiosk, the transaction moves to the mobile device for completion. A push message on the mobile device launches the service provider's mobile application and the customer completes the transaction quickly and securely using the advanced automation functions, such as biometrics, GPS, wallet, camera or near field communication, available on the mobile device.
