Abstract
The object of the present invention is to provide an article management method by which detecting the location of an object is performed easily and introduction costs for detecting the location of an object are suppressed. The article management method includes a first RF chip attached to an article, a first reader/writer into which a shared memory portion and a second RF chip are incorporated, and a second reader/writer. The first reader/writer obtains information stored in the first RF chip, the shared memory portion retains the obtained information about the first RF chip, the second RF chip reads out that information about the first RF chip stored in the shared memory portion, the second reader/writer, by the second RF chip, obtains the information about the first RF chip and information stored in the second RF chip and information about the location of the second RF chip.
