Abstract
A card reader with power-saving function is used for being inserted with a memory card so that a computer can access the memory card through the card reader. When the memory card is inserted in the card reader, the card reader is enabled to operate. On the other hand, when the memory card is not inserted in the card reader, the card reader enters to a power-down mode for saving power.
