Message multiplexing method, device and corresponding program

摘要

A method is provided for multiplexing messages exchanged between a payment terminal and a communication terminal via a connection between the payment terminal and the communication terminal using the iPod Accessory Protocol, iAP. The method includes: an initialization step of initializing an external communication interface with the communication terminal, a first transmission step of transmitting, to the communication terminal, a request for creation of remote virtual channels via the external communication interface; a creation step of creating, within the payment terminal, local virtual channels corresponding to the remote virtual channels; and a second transmission step of transmitting data frames associated with the local virtual channels via the external communication interface.
