Abstract
An electronic device has a host with a card-receiving slot, with the host being capable of receiving and operating low voltage-low current (3.3 volts and no more than 0.12 amp) cards, low voltage-high current cards, high voltage (5 volts)--low current cards, and high voltage-high current cards. The inner end of the slot has a voltage-discriminating first side and an opposite current-discriminating second side. Each side has a switch with an actuator lying at a location that is occupied by a discrimination key portion that is present in one kind of card (low voltage or low current) but not in another kind of card (high voltage or high current). The electronic device has different circuits for energizing or rejecting the types of card sensed by the switches.
