Abstract

A portable terminal includes a near-field communication (NFC) device for performing information communication via near-field communication; a write button; and a read button. In order to write information stored in the portable terminal into an information providing apparatus, a user moves the portable terminal close to the information providing apparatus such that a distance between the portable terminal and the information providing apparatus is 10 cm or less while pressing the write button. In order to read information stored in the information providing apparatus into the portable terminal, a user moves the portable terminal close to the information providing apparatus such that a distance between the portable terminal and the information providing apparatus is 10 cm or less while pressing the read button.
