A method for the processing, by a transaction-processing server, of a transaction at least partially initiated from a communications terminal connectable to the server by using a communications network. This method includes: creating a secured communications channel with the communications terminal; instantiation, within an execution server on the communications network, of a virtual payment terminal capable of exchanging information with the communications terminal by using the secured communications channel; and processing a transaction between the communications terminal and the virtual payment terminal implementing at least one secure element of the communications terminal, the secure element being configured to exchange an identifier of the type of service.

Method for processing a transaction from a communication terminal

A transaction device for securing a transaction includes an NFC controller, a communication interface, an application processor, a display and a user input device. The NFC controller is configured to receive, via a contactless NFC interface, data related to the transaction from an external device. The communication interface is configured to receive an application program for the transaction device. The application processor is coupled to the NFC controller and configured to process the application program. The display is coupled to the application processor and configured to display transaction information. The user input device is linked to the NFC controller and configured to receive a user acknowledgement of the transaction. The NFC controller is further configured to transmit, via the contactless NFC interface, a transaction agreement of the transaction to the external device in response to the user acknowledgement from the user input device, without the user acknowledgement and the transaction agreement being routed through the application processor.

Transaction device and method for securing a transaction between the transaction device and an external device

A method for securing a transaction between a transaction device and an external device is described. The transaction device includes a communication controller, an application processor, and an input device. The method includes requiring the user to enter agreed transaction data via the input device, monitoring the transaction data designated to be sent to the external device or received from the external device, and preventing the transaction data designated to be sent from being sent to the external device if the transaction data designated to be sent is different from the agreed transaction data, or rejecting the received transaction data if the received transaction data is different from the agreed transaction data.

Method for securing a transaction performed with a programmable portable device

The invention relates to a method of conducting a transaction between an NFC device and a contactless integrated circuit of the passive reader type. The method includes providing, in the contactless integrated circuit, at least one reader application emulation program and, by an intermediary unit of the NFC device, establishing a communication with the contactless integrated circuit, receiving from the contactless integrated circuit reader application commands and transferring the commands to the first host processor, and receiving card application responses supplied by the first host processor and transferring the responses to the contactless integrated circuit.

Method of conducting a transaction using an NFC device

The invention relates to a user interface-equipped computing device comprising means for implementing a series of applications, said means including two execution spaces. According to the invention, the applications of the second execution space (, P, P) have a level of security specifically higher than that of the applications of the first execution space (, P, P), said two execution spaces being hosted by a physical processing means which is designed such that it cannot be separated into two parts without destroying the physical processing means.
