ABSTRACT:
A novel card read and write process for use in a single card read and write device constructed in a data processing terminal for enabling the card read and write device to access both types of IC card including a smart card and a memory card in a cost-efficient manner. The process requires the single card read and write device to determine whether the type of card inserted into a card insertion slot of the data processing terminal is one of the smart card and the memory card by detection of an answer-to-reset (ATR) signal in order to perform read and write operations in accordance with the type of IC card determined.
