Non-volatile memory card with autarkic chronometer

Abstract: A non-volatile memory card is described, which comprises a chronometer powered by an autarkic, card-internal power supply with a long-term energy store. The chronometer is connected to a card internal controller, such that the chronometer can provide the current time to the controller independent of a host system.

Eine Speicherkarte, ihre Herstellung und eine Mobiltelefonvorrichtung mit einer Speicherkarte

Abstract: Eine Speicherkarte (1) mit einer Vielzahl von Zuleitungen (8) und einem oder mehreren Kontaktelementen (9) aus einem Leiterrahmen (2) sowie einem Chip (12). Der Chip (12) ist an mindestens eine Teilmenge der Zuleitungen gekoppelt und weist einen ersten Kontakt (13) und einen zweiten Kontakt (14) auf. Die Speicherkarte (1) umfasst weiterhin eine auf den Zuleitungen (8) platzierte Antenne (15), wobei die Antenne (15) elektrisch von den Zuleitungen (8) isoliert ist. Die Antenne (15) weist ein erstes Ende (16) und ein zweites Ende (17) und mindestens eine Schleife auf. Die Antenne (15) ist konfiguriert zum Empfangen oder Senden elektromagnetischer Wellen. Der erste Kontakt (13) des Chips (12) ist an das erste Ende (16) der Antenne (15) gekoppelt und der zweite Kontakt (14) des Chips (12) ist an das zweite Ende (17) der Antenne (15) gekoppelt. Die Zuleitungen (8) und der Chip (12) und die Antenne (15) sind von einer Formmasse umschlossen und eine Oberflache der Kontaktelemente (9) liegt frei.

Memory card, the fabrication thereof and a mobile phone apparatus having a memory card

Abstract: A memory card ( 1 ) includes a multiplicity of leads ( 8 ), one or more contact elements ( 9 ) and a chip ( 12 ). The chip ( 12 ) is coupled to at least a subset of the leads ( 8 ) and has a first contact ( 13 ) and a second contact ( 14 ). The memory card ( 1 ) further includes an antenna ( 15 ) placed on the leads ( 8 ). The antenna ( 15 ) is electrically isolated from the leads ( 8 ). The antenna ( 15 ) has a first end ( 16 ) and a second end ( 17 ) and at least one loop. The antenna ( 15 ) is configured to one of receive and send electromagnetic waves. The first contact ( 13 ) of the chip ( 12 ) is coupled to the first end ( 16 ) of the antenna ( 15 ) and the second contact ( 14 ) of the chip ( 12 ) is coupled to the second end ( 17 ) of the antenna ( 15 ). The leads ( 8 ) and the chip ( 12 ) and the antenna ( 15 ) are molded and a surface of the contact elements ( 9 ) is exposed.

Data storage medium such as a storage card for an MP3-player, digital camera, etc. has an area in which information concerning the embedded integrated circuit or housing is contained such that it is not visible to the end user

Abstract: Data medium with an integrated electronic circuit in which data can be stored or is stored. The data medium has a housing (1) in which the circuit is embedded. The housing has a plate-type design with an area (3) to which a label can be glued. An identifier is also provided in the label area that provides information about the integrated circuit and or the housing.

Portable data carrier arrangement

Abstract: The invention relates to a portable data carrier arrangement that comprises a data memory and a control unit which are designed as integrated circuits respectively. The control unit is provided with means for establishing a connection to an external write and read unit, whereby said control unit generates at least one analogous signal.

Power negotation for small rfid card

Abstract: A memory card compatible RFID card includes a smartcard controller that receives power from a host device. The RFID card also includes a small inductive device capable of inductive coupling with an RFID reader. The small inductive device is small enough to fit in the form factor of a memory card. Commands may be sent to the RFID card to keep the RFID card powered.

Pos payment terminal and a method of direct debit payment transaction using a mobile communication device, such as a mobile phone

Abstract: A payment terminal using a mobile communication device ( 4 ), such as a mobile phone, is located on a removable memory card ( 1 ), e.g. type microSD card, which is adjusted in such a way so it can be inserted into an additional hardware slot, e.g. memory slot. A payment POS terminal application runs on a removable memory card ( 1 ), which contains at least one payment card. The payment card's unit ( 7 ) with the card's payment application is located in the secured part of the memory, separately from the terminal's configuration data unit ( 6 ). The configuration data of the terminal's selected identity and the payment card's data are located in the separate parts of the secure element or in completely independent secure elements or they can also be localized in the Sales Device of the merchant and there e.g. within the ICC card ( 29 ) or SAM card ( 42 ).

The electronic payment application system and payment authorization method

Abstract: The system contains a virtual POS terminal's unit in the user's personal device. The mobile communication device (1) contains a virtual POS terminal's unit (4) and also a removable memory card (3), on which there are at least two physically separate secure elements (2) stored. The removable memory card (3) is connected to the secure element (2) containing the secured part of the virtual POS terminal. The mobile communication device (1) and/or the separate portable element (6) is adjusted in such a way to be able to connect to a remote payment procession server. The removable memory card (3) and the separate portable element (6) can be equipped with the NFC communication element. Depending on the user choice, a corresponding secure element (2) with the selected payment card unit (14) is activated on the removable memory card (3). The user's payment card's identification data are supplemented by the payment receiver's identification data and also by a one-time password that was created in the one-time password unit.

Smartcard performance enhancement circuits and systems

Abstract: An RFID card includes a smartcard controller that receives power from a host device. The RFID card also includes a small inductive device capable of inductive coupling with an RFID reader. The small inductive device is small enough to fit in the form factor of a memory card or SIM card. Enhancement circuits enhance the usable read and write distance of the RFID card.
