Abstract
In exemplary embodiments, a reader device is powered on only when a card is inserted in the reader device, thereby reducing the amount of time the reader device is powered and consequently reducing the amount of power consumption by the reader device. In some embodiments, inserting the card causes power-on of the reader device, while in other embodiments, insertion of the card plus other criteria are required to power on the reader device (e.g., having the reader device connected to the host device, or operating a manual switch while the card is inserted in the reader device).
