Abstract
A connector that is configured to receive a smart card includes: a first contact configured to receive a power supply voltage and corresponding to a first (power supply) contact area of the smart card, a second contact configured to receive a reference voltage and corresponding to contact a second (reference voltage) contact area of the smart card, and a third contact corresponding to a three-state (input/output) contact area of the smart card. A first light-emitting diode having an anode coupled to the third contact and a cathode coupled to the second contact. A second light-emitting diode has a cathode coupled to the third contact and an anode coupled to the first contact. Turning on/off of the first and second light-emitting diode is controlled by the smart card through the signal at the three-state (input/output) contact area.
