Smart Card Reader

Smart cards vary widely (some are microprocessor based, some are memory only; all may have security). In addition, memory cards have data organization and microprocessor-based cards have a file structure that is defined by the application. Most smart card operating systems (inside the smart card) do not provide a method of “reading the directory (file structure)”. The file structure and security features are unique to the application. So although the reader gives access to “standard card types” (as defined in ISO-7816), it is not possible to “automatically” read and buffer the smart card data. Each application should have a predefined card type as well as use of that card; the handheld should then have that knowledge. The application, then, might choose to handle a microprocessor-based smart card as follows:

∙Handheld prompts the user to insert their card

∙User inserts the smart card into the card reader slot waking up the reader

∙Handheld polls the reader looking for the card to be inserted

∙Handheld commands reader to power up the card; reader returns the card’s answer to reset (unique to each card type)

∙Handheld commands reader to pass commands and data to the card, selecting files and providing passwords and cryptographic keys as required.

∙Reader returns smart card’s response to each command and data sent from the handheld, allowing the handheld to determine if proper access has been attained.

∙Handheld requests data from the card, and reader returns that data

∙Handheld provides command with data to be written to the card, and the reader passes that command and data to the card and returns the card’s response

∙When the transaction is complete, the handheld prompts the reader to power down the card, then prompts the user to remove the card.
