Abstract:
1. Paper money comprising: an integrated circuit having at least a first nonvolatile memory and a second nonvolatile memory, and a program memory; wherein the first nonvolatile memory is configured to store product-specific information; the second nonvolatile memory is configured to store information used for controlling reading of the information stored in the first nonvolatile memory and writing of new information to the first nonvolatile memory; the program memory includes a program by which reading of the information stored in the first nonvolatile memory and writing of new information to the first nonvolatile memory are controlled by a result of comparing in the integrated circuit the information stored in the second nonvolatile memory with information read into the integrated circuit from an external device; in a case where the information stored in the second nonvolatile memory is the same as the information read from the external device, a program for converting the information stored in the first nonvolatile memory into signals is started and the signals are transmitted to the external device; and in a case where the information stored in the second nonvolatile memory is different from the information read from the external device, the program is completed.
