![](/files/83Li3jOk5L8VzSD1e0vt) Swipe instructions showing ![](/files/BjcCsjbrXtqfecDtOWNH) “Visa Debit” option showing after swiping to find it
{% endcolumn %}

{% column %}
**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.

\
**Accessibility mode gestures**

Swipe left or swipe right to reveal the next available option and hear its content vocalized. Upon revealing the option, the terminal will announce “showing”. When the desired option is heard, double-tap anywhere on the screen or press the tactile accessibility button on the side of the terminal to select the shown option. Terminal will announce “selected” and move on to the next step in the transaction flow. Option cards that are swiped away will be heard again in the next “round” as the customer continues to swipe through the options; thus, erroneous swipes can be corrected easily.

\
**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
