    摘要: The invention relates to an electronic payment terminal (30) comprising a first USB connection port (13) comprising at least one first wire (D+″) for data transfer. The payment terminal comprises, furthermore, a first resistor (24) linking the first wire to a first source (VDD) of a first potential and a switch (38) between the first wire and the first resistor or between the first resistor and the first source.
