Abstract

The present disclosure provides a near-field communication system and a terminal. The system includes: a first terminal having a first near-field communication region; and a second terminal having a second near-field communication region, where the second near-field communication region has a first subunit and a second subunit, and the first subunit and the second subunit are configured to detect a distance between the first near-field communication region and the second near-field communication region, and the second subunit is configured to establish communication with the first near-field communication region when the distance between the first near-field communication region and the second near-field communication region is less than or equal to a preset distance. Embodiments of the present disclosure may reduce signal attenuation and external interference in data transmission.
