select_app

Description
If there are multiple Application Identifiers (AIDs) to choose from, the customer will be asked to chose between the AIDs. If there is only one AID or if the terminal can choose the AID based on the priority list, then this will be skipped and AID will be selected automatically. This will only be shown for chip cards. Contactless transactions will select the application with the highest priority.
Error Scenarios
If the customer removes the chip card, the transaction will be cancelled and no reversal will be generated
If the Application Identifier (AID) that the customer selected fails, the customer will be asked to chose from remaining AIDs. If no other valid AIDs are available, the customer will be asked to fallback to swipe the card
If the customer cancels the transaction, Transaction Cancelled, user aborted message will be shown
If the screen times out, Transaction Aborted, user timeout message will be shown
If the device crashes or device reboots while on this screen, when the payment application restarts or device boots up, no power failure recovery will happen
