Abstract: Provided is a technology for solving a problem of a high cost due to a redundant investment and improving the user's operability. An in-vehicle information system according to one embodiment includes: an in-vehicle information terminal to be mounted in a vehicle; a portable information terminal equipped with a touch panel for providing the in-vehicle information terminal with operation unit and communication unit; the operation unit for enabling a display screen of the in-vehicle information terminal to be operated by operating the touch panel of the portable information terminal when the portable information terminal is connected to the in-vehicle information terminal via an interface; and the communication unit for enabling external communication of the in-vehicle information terminal by using the communication unit of the portable information terminal.

Abstract: There is provided an article position management system which can determine where an article is present with high accuracy and manage the position of the article such that no article is left unchecked. Illumination sections (11-14) optically transmit pieces of positional information only to specific regions (lighting ranges (401-404)). A terminal device (31) receives the pieces of positional information transmitted from the illumination sections (11-14) and reads out article IDs from RFID tags (201-206) put on articles (101-106). The terminal device (31) sends the pieces of positional information and article IDs to a server (51) through a wireless LAN base station (41). The server (51) stores the pieces of positional information and article IDs sent from the terminal device (31) such that the pieces of positional information and article IDs are associated with each other.
