    Abstract: The present invention provides a method and apparatus for protecting an Encrypting PIN Pad (EPP) (100) against tampering. The apparatus provides an EPP (100) comprising a first layer (206) comprising at least two spaced apart electrode elements (218, 318 or 418), and a second layer (220 or 450) comprising at least one bridge element for electrically bridging a space (219 or 321) between the at least two electrode elements (218, 318, or 418) when the first layer (206) and the second layer (220 or 450) are urged together.

    Abstract: The invention relates to a pressure sensor in the form of a film, comprising a first carrier film and a second carrier film which are arranged at a certain distance from each other by means of a spacer. The distance holder comprises at least one recess which defines an active region of the pressure sensor wherein both of the carrier films are arranged opposite each other, also comprising a first electrode and a second electrode and a layer made of pressure-sensitive material. The first electrode, the second electrode and the layer made of pressure-sensitive material are disposed in the active region on the first and/or second carrier film such that when the carrier films are pressed together through the pressure sensitive layer, electric contact is produced between the first and the second electrode. According to the invention, the pressure sensor comprises at least one third electrode which is disposed in the active region of the pressure sensor on the first and second carrier film such that when the carrier films are pressed together though the pressure sensitive layer, electric contact is produced between the third electrode and the first electrode and/or between the third electrode and the second electrode.

    Abstract: A pressure sensor comprises a first and a second terminal for connecting it to a read-out circuit, a resistive conductor and at least two pressure-actuatable switching elements. These at least two switching elements have different turn-on pressures, such that each of the at least two pressure-actuatable switching elements is in a substantially insulating state if an external pressure applied to the pressure sensor lies below the respective turn-on pressure and in a substantially conductive state if the external pressure applied to the pressure sensor lies above the respective turn-on pressure. The at least two pressure-actuatable switching elements and the resistive conductor are connected between the first and second terminal in such a way that an electrical resistance between the first and second terminal decreases when the pressure applied to the pressure sensor goes over one of the turn-on pressures.
