1. A device for detecting presence of an electronic payment terminal on a receiving dock comprising a connector to co-operate with a complementary connector of the electronic payment terminal, said connector of said receiving dock comprising at least one series transmission pin for a transmission of signals from said electronic payment terminal to said receiving dock, said device for detecting presence comprising:
at least one presence-signaling circuit having a first state signaling a presence of said electronic payment terminal on said receiving dock and a second state signaling an absence of said electronic payment terminal on said receiving dock;
a driving circuit configured to switch the at least one presence-signaling circuit between the first and second states as a function of a voltage on said series transmission pin, said driving circuit having an input connected to said series transmission pin, an output connected to an input of the presence-signaling circuit, and controlling a voltage and/or a current at the output of the driving circuit so as to:
drive the at least one presence-signaling circuit in the first state when a level of the voltage at the input of said driving circuit is lower than or equal to a first pre-determined threshold, and
drive the presence-signaling circuit in the second state when a level of the voltage at the input of said driving circuit is greater than the first pre-determined threshold and lower than or equal to a second pre-determined threshold;
a filter connected to the output of the driving circuit, which filters an electronic signal at the output of said driving circuit, said filter comprising a capacitor having a charging time configured to maintain said presence-signaling circuit in the first state, when said presence-signaling circuit is in the first state and when the level of the voltage at the input of said driving circuit becomes temporarily greater than said second pre-determined threshold; and
an idle voltage maintaining circuit comprising an input connected to said series transmission pin and delivering a voltage substantially equal to a pre-determined idle value at an output of the idle voltage maintaining circuit.
