Problems solved by technology
In this regard, there is the problem that the user cannot firstly verify with confidence based on the obtained data carrier whether it is still in the unused and untampered delivery state or preoperational state intended by the issuer of the data carrier
The user is therefore unable to distinguish between an unsecured data carrier that has been initialized and a secure data carrier that has not been initialized

Embodiment Construction
[0046] figure 1 Show that the user is on a portable data carrier (for example, figure 2 The steps of the method of initial operation of the USB chip card with USB memory interface 21 shown in 1). The USB chip card 1 is designed for the user to put into use for the first time after receiving it, connect the USB card 1 to the USB interface of the terminal device, and load the user's intention and useful data stored on the USB card 1 to the terminal device.
[0047] Although the USB interface is particularly suitable for the present invention due to its wide use and simple handling, the present invention is not limited to the USB interface. Therefore, the present invention can be applied to any portable data carrier with any memory interface in principle, for example, it is also applied to a secure memory card, a multimedia card, a SIM mobile radio card, an SD card, etc. The present invention is also not limited to card-shaped data carriers, such as the USB chip card in the ID1 car...

In a portable data carrier having a non-volatile memory, a memory controller and a memory interface, an effected initial operation of the data carrier is checked through a request to a security unit of the data carrier via a security interface connected to the security unit. For this purpose, the data carrier comprises a memory portion comprising the memory interface and a body portion comprising the security interface, which are interconnected such that the memory portion can be folded out of the body portion, so that simultaneously the memory interface is laid open for a connection to an end device and the electrical connection between the security unit and the security interface is disconnected irreversibly.
Description
Technical field [0001] The invention relates to a method for initial operation of a portable data carrier, a portable data carrier and a method for manufacturing such a data carrier. Background technique [0002] For secure data transmission, portable data carriers with non-volatile memory (for example, USB tokens, flash memory elements, etc.) are often used, which can be connected to a terminal device via a preferably standardized interface so that the device can be read from the memory Useful data. This kind of data transmission is also used by institutions and companies (for example, manufacturers or publishers of products related to telecommunication technology and / or information technology (such as electronic and possibly portable terminal equipment or software)) in order to make important useful data (For example, update data for product, firmware update or software update, access data, etc.) The approved data carrier publisher is directly or indirectly available to users ...
