An article management method comprising steps of:

• attaching a first RF chip to an article;
• moving a moveable object equipped with a first reader/writer close to the first RF chip and obtaining information stored in the first RF chip by a first reader/writer, wherein the first reader/writer further comprises a shared memory portion and a second RF chip;
• retaining information about the first RF chip retrieved by the first reader/writer in the shared memory portion;
• reading out the information about the first RF chip from the shared memory portion by the second RF chip;
• and
• retrieving the information about the first RF chip and information stored in the second RF chip and obtaining information about a location of the second RF chip by a second reader/writer.

An article management method comprising steps of:

• attaching a first RF chip to an article;
• disposing the article on an article management shelf;
• retrieving information stored in the first RF chip by a first reader/writer attached to the article management shelf, wherein the first reader/writer further comprises a shared memory portion and a second RF chip;
• retaining information about the first RF chip retrieved by the first reader/writer in the shared memory portion;
• reading out the information about the first RF chip from the shared memory portion by the second RF chip;
• and
• retrieving the information about the first RF chip and information stored in the second RF chip and obtaining information about a location of the second RF chip by a second reader/writer.

An article management system comprising:

• a first RF chip attached to an article;
• a first reader/writer performing transmission and reception of a signal with the first RF chip, wherein a first reader/write comprises a reader/writer portion, a shared memory portion, and a second RF chip;
• and
• a second reader/writer performing transmission and reception of a signal with the second RF chip.

An article management system comprising:

• a first RF chip attached to an article;
• a first reader/writer retrieving information stored in the first RF chip,
• a shared memory portion retaining the information stored in the first RF chip that is retrieved by the first reader/writer;
• and
• a second RF chip reading out the information stored in the first RF chip that is retained in the shared memory portion;
• and
• a second reader/writer retrieving the information stored in the first RF chip and information stored in the second RF chip and obtaining information about the location of the second RF chip,
• wherein the shared memory portion and the second RF chip are incorporated into the first reader/writer.
