Patent number: 8899486Abstract: The invention relates to a data carrier (100) with a chip (10) which stores energy (13) as well as information for contact-bound or contactless inductive communication, and with a plurality of excitable chip sensors (11) integrated in the chip (10), which, after excitation (12), pass on a signal (18) to a CPU (19) of the chip (10), in which the signal (18) is processed. The invention is characterized in that, independently of storing energy (13) as well as information by the chip (10), the excitation (12) is specifically adjustable by the chip (10) for the purpose of additionally storing information and is adaptable to the requirements of processing the signal (18) in the CPU (19).Type: GrantFiled: December 6, 2005Date of Patent: December 2, 2014Assignee: Quotainne Enterprises LLCInventors: Manfred Paeschke, Kim Nguyen, Oliver Muth, Michael Knebel, Mathias Wagner, Thomas Wille

Patent number: 8583880Abstract: A method for secure data reading and a data handling system is provided. The method protects the data reading from fault attacks by repeating read request in an interleaved manner, in particular the method comprises the steps of (M200) dispatching a first read request; (M400) dispatching a second read request; (M600) dispatching a further first read request; and (M1000-a) producing an anomaly signal if a first result produced by the memory in response to the first read request does not agree with a further first result produced by the memory in response to the further first read request.Type: GrantFiled: April 29, 2009Date of Patent: November 12, 2013Assignee: NXP B.V.Inventors: Mathias Wagner, Ralf Malzahn

Patent number: 8441340Abstract: A contactless tag reader device comprises upper and lower electrodes which together define a tag location zone between them in which multiple tags can be placed. The lower electrode and the upper electrode are offset from each other such that they substantially do not overlap. This structure is used to sandwich tags vertically between two horizontally (laterally) offset reader electrodes. This enables power coupling and data transfer using capacitive coupling.Type: GrantFiled: March 14, 2011Date of Patent: May 14, 2013Assignee: NXP B.V.Inventors: Franz Amtmann, Thomas Wille, Hauke Meyn, Mathias Wagner
