The invention provides an electronic near-field communication system generating dynamic patterns. The electronic near-field communication system comprises a plurality of electronic near-field communication devices which are arranged into patterns at short range. The electronic near-field communication system is characterized in that the first electronic near-field communication device controls the working state of at least one adjacent second electronic near-field communication device by sending a preset encoded near-field signal; and the second electronic near-field communication device responds to the preset encoded near-field signal sent by the first electronic near-field communication device to change the working state, and therefore the electronic near-field communication system generates a dynamic mode. According to the invention, the electronic near-field communication system formed by the plurality of electronic near-field communication devices distributed in space can generate a dynamic pattern effect.
