An information storage device and an information storage and reproducing apparatus for facilitating the management of information about products and users. A storage device 1 receives an electromagnetic wave through its receiving antenna 11, and produces a DC current, which powers the constituting elements in the storage device 1. A central processor unit 13 thus powered reads the information in a memory 14 and feeds it via a transmitting module 15 to a transmitting antenna 16, which in turns transmits the information on an electromagnetic wave. A scanner 2 transmits the electromagnetic wave through its transmitting module 26 and transmitting antenna 27 to energize the storage device 1, while receiving, through its receiving antenna 21 and receiving module 22, the electromagnetic wave transmitted by the storage device 1. A central processor unit 23 processes the received signal, namely the information stored in the storage device 1, and displays it on a display unit 25.
