In step S1, portable information terminal 1 further receives character information and image information. Next, the portable information terminal 1 determines whether or not communication with the authentication device 3 is possible (step S2). If it is determined that the portable information terminal 1 cannot communicate with the authentication device 3, the process returns to step S1. When it is determined that the portable information terminal 1 can communicate with the authentication device 3, the portable information terminal 1 transmits control selection information to the authentication device 3 (step S3). In step S3, portable information terminal 1 further transmits character information and image information to authentication device 3.

FIG. 8 is a diagram for explaining an operation processing example of the authentication device. The authentication device 3 is a portable information terminal. It is determined whether control selection information is received from terminal 1 (step Sl l). If the authentication device 3 receives the control selection information from the portable information terminal 1 and determines that it is not, the process returns to step S 1. When it is determined that the authentication device 3 has received the control selection information from the portable information terminal 1, the authentication device 3 displays the arrangement image 30 (step S12). When the arrangement image 30 is displayed, the electronic paper 2 is superimposed on the authentication device 3 by the operator of the electronic paper 2. The authentication device 3 executes position authentication processing (step S13), and determines whether or not the overlap of the electronic paper 2 is detected at a predetermined position (step S14). If the authentication device 3 detects the overlap of the electronic paper 2 at a predetermined position and determines that it is not, it waits for a certain time (step S16) and then returns to step S13. When the authentication device 3 determines that the superposition of the electronic paper 2 is detected at a predetermined position, the authentication device 3 transmits display instruction information to the electronic paper 2 (step S15).

FIG. 9 is a diagram for explaining an example of an electronic paper operation process. The electronic paper 2 determines whether display instruction information has been received from the authentication device (step S21). If it is determined that the display instruction information is not received from the electronic paper 2 authentication apparatus 3, the process returns to step S21. If the electronic paper 2 determines that the display instruction information has been received from the authentication device 3, the electronic paper 2 determines whether the position of the authentication device 3 is a predetermined position (step S22). Then, the location authentication process for the authentication device 3 is performed.
