INFORMATION PROCESSING DEVICE, FUNCTION EXPANSION UNIT, AND INFORMATION PROCESSING SYSTEM

摘要

The object is to ensure security when coupling an information device and a function extension unit. An information processing apparatus (10) includes a memory unit (11), a receiver unit (12), and a control unit (13). The memory unit (11) stores unit identification information indicating a function extension unit (20) that is permitted to transmit and receive data. When adjacent to the function extension unit (20), the receiver unit (12) receives unit identification information indicating the function extension unit (20) from the adjacent function extension unit (20) by wireless communication. When the received unit identification information is identical with the unit identification information stored in the memory unit (11), the control unit (13) permits data transmission and reception with the adjacent function extension unit (20) via the wired transmission channel (14, 23).
