Abstract:
The invention relates to a payment device 100 comprising a secure integrated circuit SE with a dual interface. A connector 110 is connected to the contact type interface in order to communicate with an external reader. An antenna 140 is connected to the contactless interface. The device also comprises a reader circuit 120, 130, 150 compatible with the secure integrated circuit SE, wherein the reader circuit is connected in parallel to the connector 110. An independent battery BAT is used to power the reader circuit. A power switching circuit 160 connected to a communication field detection circuit 170, wherein said power switching circuit is capable of powering the reader circuit after a communication field is detected.
Abstract:
The invention relates to a device (CD) comprising a capacitive key-board (KB) constituted of a plurality of keys (KY), each key comprising an active electrode (AEL) and an active ground plane (AGP), a microcontroller (MC) connected to said keyboard (KB) through active electrode (AEL) and active ground plane (AGP). Said microcontroller (MC) is adapted for managing said keyboard (KB) in a reverse manner for emulating a sequence of tactile contacts on a capacitive screen.
Abstract:
The present invention relates to a method and system for securing a validation process of an online payment transaction. During an online transaction on a mobile device, it is requested a contactless tap from a contactless display card (thanks to NFC reader mode in the mobile device) to establish a contactless exchange session. During this contactless exchange session, the display card receives the amount requested for the transaction and the identification of merchant. The user is invited to check amount and merchant identification on the screen of the display card. When the user validates the transaction by for example pressing on a corresponding button then the display card creates an authorization message comprising enciphered financial user information and data on the transaction. With a second tap from the display card, the mobile device receives the authorization message which is transmitted to the display card issuer through the merchant for validation.
Abstract:

The communication device further comprises a light sensor 11 for receiving a light signal 30.
Abstract:
The invention relates to a magnetic field transformation device comprising a battery, a processing unit, an antenna coupled with the processing unit and capable of exchanging data according to the standard ISO14443, a coil coupled with the processing unit and capable of radiating a low-frequency electromagnetic field corresponding to a succession of bits emulating the passing of a magnetic stripe.
Abstract:
The invention relates to a method for controlling contactless transactions of contactless applications stored on a first secure element, said contactless transactions being operated with a portable device, said portable device comprising said first secure element. The method is characterised in that it comprises a step of pairing said first secure element with a second secure element, a step of requesting to the second secure element an authorization to execute a predetermined number of contactless transactions, a step of requesting to the second secure element another authorization to execute a new predetermined number of contactless transactions when a predetermined contactless transaction's threshold is reached.
