Abstract
A noncontact communication medium includes a power generator that has a coil and generates power with application of an external magnetic field from an outside to the coil, a clock signal generator that generates a clock signal using the power, a processor that operates using the power and executes processing on a command included in the external magnetic field. The clock signal generator makes a frequency of the clock signal lower as intensity of the external magnetic field is smaller, in a period except for a processing period in which the processor executes the processing.
Claims7
A noncontact communication medium comprising:
- a power generator that has a coil and generates power with application of an external magnetic field from an outside to the coil;
- a clock signal generator that generates a clock signal using the power;
- and
- a processor that operates using the power and executes processing on a command included in the external magnetic field,
- wherein the clock signal generator makes a frequency of the clock signal lower as intensity of the external magnetic field is smaller, in a period except for a processing period in which the processor executes the processing.
An operation method of a noncontact communication medium including a power generator that has a coil and generates power with application of an external magnetic field from an outside to the coil, a clock signal generator that generates a clock signal using the power, and a processor that operates using the power and executes processing on a command included in the external magnetic field, the operation method comprising:
- making a frequency of the clock signal lower as intensity of the external magnetic field is smaller, in a period except for a processing period in which the processor executes the processing.
A non-transitory computer-readable storage medium storing a program that is executable by a computer, which is applied to a noncontact communication medium including a power generator that has a coil and generates power with application of an external magnetic field from an outside to the coil, a clock signal generator that generates a clock signal using the power, and a processor that operates using the power and executes processing on a command included in the external magnetic field, to perform processing comprising:
- making a frequency of the clock signal lower as intensity of the external magnetic field is smaller, in a period except for a processing period in which the processor executes the processing.
