A method, module and device for near field communication

Abstract

This specification provides a method, module, and device for near-field communication. The solution includes: a slave device acquiring interaction state information generated under the action of a master device; based on the interaction state information, determining whether the master device meets preset conditions; the preset conditions indicating that the master device intends to engage in near-field communication with the slave device; if the preset conditions are met, the slave device is set to a first gain mode with high communication performance; if the preset conditions are not met, the slave device is set to a second gain mode with low communication performance. This reduces the probability of false triggering and improves communication security.
