Abstract
In receiving information on an item by use of electromagnetic waves propagating from the item in which a radio frequency identification (RFID) chip is embedded, a portable handset requests the information on the item that is stored in the RFID chip to the RFID chip-embedded item, receives from the item the information on the item, and, if additional information is needed other than the received information, requests the additional information to a server storing the information on the item by using the received information.
