Abstract:
A device (1) with a data carrier module (3) which is arranged for contactless communication with a communication station, and includes a holding means (4), andan integrated circuit (6) which is arranged on the holding means (4) at the area of a holding surface (5) of the holding means (4) and is provided with at least two circuit connection contacts (7, 8), andalso includes a protective cap (10) of an electrically insulating material which protectively covers the integrated circuit (6), andincludes a transmission coil (11) which is also arranged on the holding means (4) at the area of the holding surface (5) of the holding means (4), andhas at least one coil turn (12) and two coil connection contacts (13, 14), each of which is connected to a respective associated circuit connection contact (7, 8), characterized in that the transmission coil (11) is covered by a protective layer (16) of an electrically insulating material, andthat a respective window (17, 18) is formed in the protective layer (16) at the area of each of the two coil connection contacts (13, 14), andthat a connection wire (19, 20) is connected between each coil connection contact (13, 14) and its respective associated circuit connection contact (7, 8), which connection wire is guided to the relevant coil connection contact (13, 14) via a window (17, 18), andthat the protective cap (10) protectively covers not only the integrated circuit (6) but also the two connection wires (19, 20) and the two windows (17, 18) as well as the areas of the two coil connection contacts (13, 14) which adjoin the two windows (17, 18).
