Abstract:
A system for avoiding an access conflict between a plurality of devices that access an IC module. The system includes a first device and a second device that can access an IC module used in an electronic money system. The second device has the function of detecting waves having a predetermined pattern to indicate that the first device is accessing the IC module. These waves may be continuously generated from the first device or may be continuously generated from another device installed near the first device, and when the second device detects the waves having the predetermined pattern, the second device refrains from accessing the IC module. This allows the system to implement autonomous conflict control between a plurality of devices that access the IC module that does not have an adequate conflict control function without providing a special control circuit.
