MESSAGE MULTIPLEXING METHOD, DEVICE AND CORRESPONDING PROGRAM

摘要

The invention relates to a method for multiplexing messages exchanged between a payment terminal and a communication terminal via a connection between said payment terminal and said communication terminal using the iPod Accessory Protocol, iAP. According to the invention, such a method includes: an initialization step (311) for initializing an external communication interface with said communication terminal, a first transmission step (312) for transmitting, to said communication terminal, a request for the creation of remote virtual channels via said external communication interface; a creation step (313) for creating, within said payment terminal, local virtual channels corresponding to said remote virtual channels; and a second transmission step (32) for transmitting data frames associated with said local virtual channels via said external communication interface.
