Abstract:
A method for selecting a communications protocol between an integrated circuit card and a terminal, the terminal being capable of communicating using at least two communications protocols, with one of the at least two communications protocols being a preferred communications protocol, the method comprising:(a) transmitting a reset by the terminal to the integrated circuit card; (b) receiving an answer-to-reset by the terminal from the integrated circuit card indicative of a first communications protocol operable in a first geographic region; (c) determining whether the first communications protocol matches the preferred communications protocol; (d) transmitting, if the first communications protocol does not match the preferred communications protocol, another reset by the terminal to the integrated circuit card; and (e) receiving another answer-to-reset by the terminal from the integrated circuit card indicative of a second communications protocol operable in a second geographic region which is larger than the first geographic region.
