Abstract:
A wireless tag processing device includes a wireless tag reader-writer and a processor configured to acquire first and second sets of parameter values, control the reader-writer to transmit a radio wave using each parameter value of the first set and acquire a first intensity of a response wave from a wireless tag, when a highest first intensity satisfies a first condition, determine a parameter value of the first set corresponding to the highest intensity as a parameter value to be used by the reader-writer, and when the highest intensity does not satisfy the condition, control the reader-writer to transmit a radio wave using each parameter value of the second set and acquire a second intensity, and when a highest second intensity satisfies a second condition, determine a parameter value of the second set corresponding to the highest second intensity as the parameter value to be used by the reader-writer.
