Initiate application processing

The terminal sends the get processing options command to the card. When issuing this command, the terminal supplies the card with any data elements requested by the card in the processing options data objects list (PDOL). The PDOL (a list of tags and lengths of data elements) is optionally provided by the card to the terminal during application selection. The card responds with the application interchange profile (AIP), a list of functions to perform in processing the transaction. The card also provides the application file locator (AFL), a list of files and records that the terminal needs to read from the card.
