Abstract
A card detection apparatus and a method for detecting insertion and ejection of a card includes a card including at least one card detection terminal. A card detection unit generates a detection signal to determine whether or not the card has been inserted using a connection time difference of the card detection terminal. A controller analyses the detection signal generated by the card detection unit to determine whether or not the card has been inserted and outputs insertion information of the card according to the determination. A data processing unit writes or reads information to or from the card according to the insertion information of the card output from the controller.
