A module for managing a transaction between a terminal and an electronic device

摘要

A transaction module can be incorporated in a terminal for authorizing a transaction between a first application resident in the terminal and a second application resident in an electronic device. The module may include code-obtaining means for obtaining a code; an interface with a communications means of the terminal enabling a validation request including the code to be sent to a secure server; means for generating an audio signal from the code; an interface with a module of the terminal suitable for sending the audio signal to a loudspeaker of the terminal in order to play it back; and means for authorizing the transaction on receiving a validation message from the secure server. The validation message may be representative of the secure server receiving the code from the electronic device.
