Provided is a card with a built-in electronic component, which has a superior button click sensation. A card of the present invention into which is built-in a module substrate upon which an electronic component has been disposed is provided with: a front cover sheet stacked upon a side above the module substrate; an adhesion layer adhering between the module substrate and the front cover sheet; and a dome switch which is disposed upon the module substrate, and by way of the card upper surface being pressed, the switch's movable portion deforms to the module substrate side so that the electrical contact comes into tactile contact with the module substrate in order to operate the card; wherein the switch's movable portion is such that the upper surface does not adhere to the adhesion layer and the deformation to the module substrate side is unrestrained with respect to the adhesion layer.

Die Erfindung betrifft ein Verfahren zur Herstellung eines tragbaren Datenträgers (1), der wenigstens eine Steuereinheit (6) und einen die Steuereinheit (6) aufnehmenden Körper (2) aufweist. Die Steuereinheit (6) ist nicht durch eine berührende Kontaktierung von außerhalb des tragbaren Datenträgers (1) zugänglich. Das erfindungsgemäße Verfahren zeichnet sich dadurch aus, dass der tragbare Datenträger (1) mit einer mit dem Reset-Eingang der Steuereinheit (6) verbundene Rücksetzeinrichtung ausgerüstet wird, die von außerhalb des tragbaren Datenträgers (1) betätigbar ist und mit deren Hilfe eine Überführung der Steuereinheit (6) in einen definierten Zustand auslösbar ist.

The invention concerns a portable object, such as a chipcard, capable of contactless communication with a reader located in the neighbourhood of said object, the object comprising an integrated circuit, an antenna (11) having first (11a) and second (11b) pads, and an object body (10). The invention is characterised in that said object further comprises a switch (17) operable by an object holder and in that, in a switched-on position of the switch, the first and second pads (11a,11b) of the antenna are electrically connected and the contactless communication with the reader is enabled whereas, in a switched-off position of the switch, the first and second pads (11a,11b) of the antenna are electrically disconnected and the contactless communication with said reader is disabled. The invention relates more particularly to contactless or dual-interface cards.

A smart card, smart card reader, and system for secure entry of a secret personal identification number (PIN) directly into the smart card while the card is presented to the reader. Because the user's PIN is entered directly into the smart card, authenticated directly by the smart card itself, and not propagated outside the smart card, the PIN cannot be covertly obtained through the use of a compromised reader or other device in the system. A PIN keypad on the smart card allows user entry of the PIN, and an authentication unit within the smart card verifies that the PIN is correct. The reader merely supplies electrical power for the smart card to take the PIN entry and perform the authentication, but does not handle the PIN itself in any way. The reader, however, is designed to allow access to the keypad on the smart card while the smart card is being presented. The smart card keypad may have identifying indicia, or alternatively may be not visible, so that photographs, logos, etc., placed on the smart card will not be obscured. In this case, the reader has an overlaying surface with the identifying indicia for the keypad. The reader may also have a separate keypad of its own for use with conventional smart cards that lack a keypad.

A noncontact IC card is provided with an antenna coil, an IC chip and a short-circuiting circuit formed on a base card. The noncontact IC card is kept inoperative unless the short-circuiting circuit is opened and the noncontact IC card is rendered operative when the short-circuiting circuit is opened. The short-circuiting circuit is formed so as to extend across a main part and a removable identification part included in the base card. The short-circuiting circuit can surely be opened by removing the identification part from the base card.

A light illumination membrane switch having a configuration with a reduced size, capable of realizing an effective light illumination of the keys and a highly reliable operation even under the high humidity environment. The switch has a light source section (100) using an LED bare chip element (26) for emitting lights to illuminate the key section (30, 31) which is directly mounted on the electrode circuit member (22) of the printed circuit board (20). The switch may includes a translucent diffuser member (33) having a cavity region (37) for directly transmitting the lights emitted from the light source section (100) to the key section (30, 31). The switch may includes a translucent diffuser member (33C) having a side wall portion (41) defining an opening such that the translucent diffuser member (33C) and the printed circuit board (20) are assembled together by inserting the printed circuit board (20) into the opening defined by the side wall portion (41). The switch may includes a translucent diffuser member (52) having reflective coating layer (54, 55) formed thereon for reflecting the lights emitted from the light source section (100) into the translucent diffuser member (52).

Contacteur électrique (1) pour carte plastique mince (10) comprenant deux bornes (2) et un élément conducteur (3) aptes à se déplacer relativement, de manière à occuper une première position où les deux bornes (2) sont isolées ou une deuxième position (12) où l'élément conducteur (3) réalise un contact entre les deux bornes (2), les deux bornes (2) étant solidaires d'une membrane élastiquement déformable (4), afin de permettre un déplacement depuis la première position vers la deuxième position (12) sous l'effet d'un appui (13) et un déplacement opposé automatique, lorsque ledit appui (13) cesse.

Procédé de fabrication d'un tel contacteur électrique (1).
