Information card having optical communication interface sections at a plurality of its surfaces and read/write device for information card having separate interface unit

摘要

An information card includes a card body having a plurality of surfaces and a plurality of optical communication interface sections provided respectively at different surfaces. A read/write device for the information card includes: a case having surfaces each processed into a prescribed shape; a main board which is provided in the case and has connectors provided respectively at positions corresponding to the surfaces; and a user interface board having a user interface section which can be joined to the main board via the connector and is fit to the prescribed shape when joined to the main board. Another read/write device includes: a case; an electronic circuit provided in the case; a connector connected to an input/output section of the electronic circuit provided to the case; and an interface unit which is provided separately from the case, and includes either one or both of an optical communication interface section and a user interface section which can be electrically connected to the electronic circuit via the connector and a cable, respectively.
