摘要： [Solving Means] A non-contact communication medium according to an embodiment of the present technology includes: a voltage generation unit; a memory unit; a clock signal generation unit; and a control unit. The voltage generation unit includes an antenna coil for transmission/reception, and receives a signal magnetic field from an external device to generate a voltage. The memory unit stores one or more circuit parameters set in the voltage generation unit, and predetermined management information. The clock signal generation unit is configured to be capable of selectively generating clock signals having two or more different frequencies. The control unit is configured to select a frequency of a clock signal to be supplied to the memory unit from the clock signal generation unit.
