Create a `UiConfiguration` Instance {#tap-to-phone-uiconfig-instance-configure-task}
====================================================================================

Use a `UiConfiguration` instance to configure the UI functionality of the Tap to Pay on Android SDK.  
You can configure these parameters in the `UiConfiguration` instance that you create:

* Configure these Summary screen features:
  * Refund a transaction (`REFUND_TRANSACTION`).
  * Send a receipt by email (`SEND_RECEIPT_VIA_EMAIL`).
  * Capture a transaction (`CAPTURE_TRANSACTION`).
  * Retry a failed transaction (`RETRY_TRANSACTION`).
  * Increment a transaction (`INCREMENT_TRANSACTION`).
    {#tap-to-phone-uiconfig-instance-configure-task_ul_mkm_dm3_lyb}
* Configure the Summary screen so that it can be skipped (`SKIP_SUMMARY_SCREEN`) or so that it closes after 5 seconds (`CLOSE_AFTER_TIMEOUT`). The default setting is to show the Summary screen.
* Configure the signature capture so that it prints on the paper receipt (`ON_RECEIPT`) or is skipped (`NONE`). The default setting is on-screen signature capture.

Follow this step to create the `UiConfiguration` instance in your app:

1. Create and configure the `UiConfiguration` instance.

   ```
   mposUi.configuration = UiConfiguration(
     summaryFeatures = setOf(
               SummaryFeature.REFUND_TRANSACTION,
               SummaryFeature.SEND_RECEIPT_VIA_EMAIL,
               SummaryFeature.CAPTURE_TRANSACTION,
               SummaryFeature.RETRY_TRANSACTION,
               SummaryFeature.INCREMENT_TRANSACTION
         )
   // Use this to skip the summary screen
   // resultDisplayBehavior = UiConfiguration.ResultDisplayBehavior.SKIP_SUMMARY_SCREEN,
   // Use this to set signature capture to be on paper receipt
   // signatureCapture = SignatureCapture.ON_RECEIPT,
   )
   ```
