The Android point-of-sale (POS) app integrates to the Tap to Pay on Android SDK.

The merchant's Android POS app sends a request to the Tap to Pay on Android SDK to process a payment.

The Tap to Pay on Android SDK user interface opens on the Android phone screen and displays prompts to guide the customer through the payment flow.

The Tap to Pay on Android SDK sends the transaction result and details to the Android POS app, which completes the transaction.
