Patent number: 11803726Abstract: A method of configuring a contactless communication device is provided. The contactless communication device includes integrated circuits hosting at least two applications compatible with different communication protocols or the same communication protocol and using different communication parameters and a contactless communication circuit. The method includes stopping, by the contactless communication circuit, the transmission of answers of the contactless communication device to requests transmitted by a proximity coupling reader during a transaction initiated by the reader to cause the initiation by the reader of a new transaction.Type: GrantFiled: June 10, 2022Date of Patent: October 31, 2023Assignees: STMICROELECTRONICS (ROUSSET) SAS, PROTON WORLD INTERNATIONAL N.V.Inventors: Olivier Van Nieuwenhuyze, Jean-Marc Grimaud

Patent number: 9894469Abstract: An NFC device includes first and second secure elements, an NFC router, and a processor. A method involves emulating, by the NFC router in response to a command from the processing device, an RF card emulation transaction. The RF card emulation transaction includes transmitting by the NFC router a command to the first and second secure elements to verify the presence of NFC transaction applications in the first and second secure elements. The method also includes receiving, by the NFC router, responses from the first and second secure elements and a new RF message from an NFC terminal. The responses indicate the NFC transaction applications stored by the first and second secure elements, and the new RF message relates to an NFC transaction. The new RF message is routed to the first or second secure element based on the responses.Type: GrantFiled: March 24, 2016Date of Patent: February 13, 2018Assignees: Proton World International N.V., STMicroelectronics (Rousset) SASInventors: Olivier Van Nieuwenhuyze, Jean Marc Grimaud, Arach Mohammed Brahim
