Abstract
Communication processing is performed so as to correspond to multiple types of contactless IC cards having different specifications, such as command classes and security algorithms. Without performing a process for a command or response result communicated with an IC card, a reading device encapsulates the command or result into a command that is called a through command and that is independent of the type of IC card and delegates the process to a controller module. Thus, the reading device is independent of the type of IC card. A command and a process procedure which depend on the type of IC card are taken care of by a replaceable software module that is provided in the controller module and that corresponds to the card.
