PROBLEM TO BE SOLVED: To improve the use efficiency of a terminal of a module such as a memory module.;SOLUTION: A module 10 comprises an IC tag 30 having a semiconductor memory 33. The wireless transmission of information DA1 on a module recorded in the semiconductor memory is performed. A reader 50 having on a socket 60 an antenna 76 for receiving a radio signal from the IC tag 30 is provided on a mother board 40. The information DA1 on the module is acquired by wireless transmission. The control of the operation of the module 10 is performed based on the information DA1 on the module acquired by the mother board 40. Means 30 and 50 for sending and receiving a signal by use of the mother board 40 and the module 10 via the side portion 66 of the socket 60 are provided.;COPYRIGHT: (C)2009,JPO&INPIT
