A method for transmitting data between a first electronic module including a general-purpose processor and a second electronic module including a secure processor, the two modules being combined in an electronic device, the first module executing a first operating system and the second module executing a second operating system, the modules each including a hybrid communication stack including, alongside components of layers 3 and 4 of the OSI model, a specialised data transmission component (ITP), connecting layers 3 and 4 of the OSI model.

Data transmission method, device and corresponding program

In the field of payment terminals, a new generation of modular, function-rich payment terminals is appearing. Such smart payment terminals transmit, equally well, data relative to payment transactions and, for example, data relative to software updates. However, at present, a smart payment terminal in incapable of transmitting different data in accordance with their respective transmission constraints. This can represent a considerable cost for the merchant. A communications device is therefore provided to set up two connections simultaneously with two different gateways and thus be capable of exchanging data associated with different transmission parameters. Thus, the communications device can simultaneously transmit data relative to different types of services having distinct transmission parameters.
