A security feature for a valuable document, includes at least one unit of information, a luminescent material designed to emphasize the unit of information being provided in the region of said unit of information.

A method is for applying an adhesive layer to a module-carrier tape provided with a plurality of chip modules including: surfaces of the chip modules being elevated concerning the surface of base areas of the module-carrier tape substantially surrounding the plurality of chip modules: forming tabs in the adhesive layer such that the tabs correspond to the chip modules or their protective layers of the module-carrier tape; connecting the adhesive layer to the module-carrier tape such that the tabs rest on the surfaces of the chip modules and sections of the adhesive layer adjoining the tabs rest on the base areas of the module-carrier tape. Also disclosed are a device for applying an adhesive layer to a module-carrier tape provided with chip modules, a module-carrier tape connected to an adhesive layer, an adhesive layer, and a method for producing a portable data carrier, and a portable data carrier.

A method and a card management system are for providing access to a virtual card, VC, the VC being issued to a user by a card issuer. The card management system includes an API management gateway and a virtual card, VC, handler. The VC handler is configured to receive through the API management gateway a request for VC credentials from the user; to fetch VC credentials; and to provide the VC credentials through the API management gateway to a card issuer app, for being pushed to the user for allowing a card non-present transaction on the card issuer app.

A card-shaped data carrier includes an electronic chip module with at least one chip and a contact structure, and including a card body with an arrangement region for receiving the chip module, the chip module being arranged in the arrangement region of the card body, and the card body having at least one first plastics layer and at least one ceramic layer, the first plastics layer being formed from a brittle plastics material to adjust a fracture behavior of the card-shaped data carrier.

The present disclosure discloses a card having an inclined or excavated edge surrounding the card or part of the surface of the card. At least a part of the inclined or excavated edge or part of the surface of the card may be coloured or in white. The revealed part may particularly be formed by means of a printing process or alternatively by way of superimposed foil layers.

A method for manufacturing a card-type data carrier has a top side and a bottom side arranged parallel to one another, and a circumferential side face that connects the top side and bottom side to one another. The side face is provided with a coloured coating in such a way that the coloured coating is spaced apart from the top side and from the bottom side along the entire circumferential side face.

Methods and devices are provided for installing and hiding applets onto smart cards devices. In a first step, a request for installing an instance of a first applet is received at the card device from an off-card entity. The request includes a first applet identifier. An applet instance is then installed with the first applet identifier in a registry of the card device's operating system. In a further step, a request for hiding the instance of the first applet identified by the first applet identifier is received at the card de-vice from the off-card entity. After receiving the hiding request, the smart card operating system finds the applet instance with the give applet identifier and hides it.

A method is implemented by a chip embedded in a chip card to adjust the internal supply voltage of the chip based on the strength of an external electromagnetic field that powers the chip. The internal supply voltage can be lowered by toggling a reduction in the threshold voltage. The chip includes a sensor register displaying a field strength value dependent on the external field strength and the adjusted internal supply voltage. Additionally, a corresponding computer program product, a storage medium containing the computer program product, a method for setting up the chip within the chip card using the storage medium to execute the method for adjusting the internal supply voltage, as well as a chip card featuring the chip, in which the method for adjusting the internal supply voltage of the chip is implemented, are also provided.

A method is provided for re-masking from a Boolean mask to an arithmetic mask with a modulus (2m*p), in which m is an integer greater than or equal to zero, and p has at least one prime divisor unequal to 2, so that a carry is generated. The carry is masked or balanced to protect it against intrusion attacks.
