Method for transmitting data to two distinct gateways, and corresponding device
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.
