摘要： A power interface circuit of a contact integrated circuit (IC) card reader is provided. The power interface circuit includes a power control unit configured to invert, amplify and output a power control signal supplied from the outside, a switching diode unit configured to control on and off operations of a ground terminal transistor in a complementary transistor unit in response to an output signal of the power control unit, the complementary transistor unit in which complementary transistors transfer a power supply terminal voltage to a power output unit or mute a card power supply terminal of the power output unit to a ground voltage level while operating inversely to each other in response to a control signal directly input from the power control unit and a control signal input through the switching diode unit, and the power output unit configured to output a voltage input through the complementary transistor unit to a card power supply terminal of an IC card or maintain the card power supply terminal at the ground voltage level in response to operation of the complementary transistor unit.

摘要： An integrated RF card reader includes an integrated RF transmission unit including a Felica chip and a Felica security unit performing a security function that is needed to process a Felica type RF card where an RF function is removed. Since a variety of types can be embodied through a single RF transmission circuit by using the integrated RF card reader, a manufacturing cost can be reduced.
