Description

If the card supports multiple accounts and the payment application was not able to determine the account by this point, the customer will be asked to select one of the accounts. Only the accounts that support the current transaction type will be presented to the customer. Note: For EMV cards where the account information can be derived from the Application Identifier (AID), the customer will never be prompted for account selection.

The standard set of vertical list options buttons will be presented with prefixed digits, starting with digit “1” for the first button, followed by “2” for the second button and so on.
