A card body for a chip card, includes a metal layer made of a steel alloy. The steel alloy of the metal layer contains 0.07 to 4 wt. % of carbon, and/or the steel alloy of the metal layer contains 0.01 to 0.3 wt. % of sulfur.

An identification card includes a ceramic substrate with opposite surfaces, and an accommodating part. A marking joint part is arranged in the accommodating part, and the orthogonal projection of the accommodating part on the ceramic substrate covers the orthogonal projection of the marking joint part on the ceramic substrate. The marking joint part includes a bearing layer and a marking part arranged on the bearing layer. The bearing layer and the marking part are of an integrated structure. The ceramic substrate is provided with an accommodating part for setting a marking joint part to ensure the flatness of the identification card, and the orthogonal projection of the accommodating part on the ceramic substrate covers the orthogonal projection of the marking joint part on the ceramic substrate.

A card body for a chip card, includes a module opening for receiving a chip module having a coil, a metal layer having a slot which extends from an outer edge of the metal layer to the module opening, and a plastic layer which is applied to one side of the metal layer. The module opening has a blind hole cut out of the plastic layer and the metal layer and an outer area which surrounds the blind hole which is cut out of only part of the height of the plastic layer. A further slot is provided in the outer region in the metal layer.

A method is for updating an operating system, OS, administering a file system in a secure element, SE. The method includes the steps of providing an update agent in the SE; assuming control of the SE by the update agent from the operating system; loading an OS image into the SE, the OS image representing an update of the operating system; providing an updated operating system by installing the OS image; and handing over control of the SE by the update agent to the updated operating system. Within this update process, the update agent provides a provisional file system in the SE and administers the provisional file system as long as the update agent is in control of the SE. A respective secure element, a respective update agent, and to a respective computer-program product employ the method.

A method and a device for upgrading an Executable Load File, ELF, having dependencies, on a Secure Element, SE. The method includes in a first step receiving a request for upgrading an ELF. The request involves a first identifier, identifying a first ELF version loaded on the SE, a second identifier, identifying a second ELF version loaded on the SE, and an upgrade option. Upon receiving the request, dependencies of the first ELF version from other ELFs loaded or stored on the SE are determined. Subsequently, if dependencies have been determined, it is checked whether the upgrade re-quest is allowed. If the update request is allowed, an upgrade session is started and the first ELF version is replaced with the second ELF version. The dependencies of the first ELF version are then linked to the second ELF version.

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.

The invention relates to a method of manufacturing a card-shaped data carrier, such as an identification card, and includes the steps of: providing a card body with printed features and with an overlay layer disposed over the printed features; providing a press tool having a profile corresponding to a predetermined shape registered to the printed features on the card body, wherein the profile is provided by an electroformed layer; and embossing the profile of the press tool in the overlay layer. A lamination plate is provided for embossing an overlay layer of such data carrier, including a profile with a predetermined shape. The profile is registered to printed features on the card body, and the profile is provided by an electroformed layer.

It is provided a method for transferring and managing data packages between a first portable secure element, SE, server implemented in a portable device ( 100, 200 ) and a second portable SE server implemented in an embedded UICC, eUICC ( 120, 240 ), comprised in a user's device ( 110, 230 ) which is local to the portable device ( 100, 200 ), the first and second portable SE severs comprising Subscription Manager, SM, functionalities, the method comprises the first and the second portable SE servers establishing off-line communication using local data transport protocols in a secured mode, the first or the second portable SE server implementing first transfer functionalities ( 140 ) for performing secure transfer of the data packages and the first or the second portable SE server implementing second transfer functionalities ( 140 ) for performing end-to-end securing of the data packages after the secure transfer of the data packages.

A method is provided for testing a card body with a metallic core layer for a contactless or dual-interface chip card, and a method is provided for manufacturing a contactless or dual-interface chip card. The method involves testing the functionality of the card body before the chip module employed for testing, or a corresponding chip module, is fixed into the cavity of the card body. A card body having impurities, a partial closure or full closure in the slot of its metallic core layer fails the test and is not used at all for fixing the chip module and for the subsequent manufacturing steps.

An OTA Edge system, constructed to: (1) receive polling requests, dedicated to an OTA Core system, from one or several mobile end de-vices; wherein an offload filter implemented in the OTA Edge system and constructed to: (2) accept polling requests from mobile end devices for which contents are present on the OTA Core system, and (2′) reject polling re-quests from mobile end devices for which no contents are present on the OTA Core system.
