Abstract: Disclosed is a method that enables a smart card to exchange data with an apparatus, which is intended to supply the smart card with a permanent clock signal in a permanent mode of operation. The method according to the invention includes the steps of detecting, in the course of the permanent mode of operation, of an impending disappearance of the permanent clock signal, wherein the detecting step includes a comparison of the value of the amplitude of the permanent clock signal with a predetermined value; and substituting an auxiliary clock signal for the permanent clock signal. The invention enables the smart card to receive, after the disappearance of the permanent clock signal, a number of clock pulses which suffices for completing pending read/write operations.

Abstract: The invention relates to a data transmission device between two separate lines. This device comprises a real terminal (TRA, TRB) and a virtual terminal (TVA, TVB) associated with each of the lines. The state of a real terminal is that of the associated line. The state of a virtual terminal indicates whether the associated line is transmitting or able to receive a data. Each real terminal associated with a line controls the state of the virtual terminal associated with the other line by means of a control signal (COM), while said virtual terminal controls the state of its associated real terminal (CTRL), and accordingly of the line. A virtual terminal associated with a receiving line receives the control signal (COM) coming from the real terminal associated with the other line and inhibits (INH) the real terminal associated with this receiving line. The inhibited real terminal of the receiving line accordingly is no longer capable of sending a control signal (COM) as long as the other line is transmitting.

A control circuit is also provided which is connected to the input of the second transistor to turn on the second transistor for providing the second current when the first current exceeds a predetermined value.
