Abstract
The portable memory medium of the invention has a memory, for storing the predetermined information which is embossed on its surface, and a CPU. When a read instruction is supplied from a portable memory medium handling system externally connected to the portable memory medium, the CPU reads out the predetermined information stored in the memory, and supplies it to the portable memory medium handling system, which then displays the information on a display unit. The operator compares the information displayed on the display unit with the predetermined information embossed on the portable memory medium, and thereby determines the authenticity of the embossed predetermined information.
