Abstract

An embodiment of the present application provides a method for selecting a modulation mode, a near-field communication device, and a storage medium. The method includes: acquiring current location information of an electronic device; determining the type of near-field communication of the electronic device according to the current location information; Communication type, which determines the target modulation method of near field communication.

Description

technical field [0001] The present application relates to the field of electronic applications, and in particular to a method for selecting a modulation mode, a near-field communication device, and a storage medium. Background technique [0002] Near Field Communication (NFC) is an emerging technology, and near field communication devices using the NFC technology can exchange data when they are close to each other. The working principle of NFC is that after receiving the field strength sent by the Reader, the NFC near-field communication device superimposes response information on the field strength to form a load modulation signal, and sends the load modulation signal back to the Reader. When the NFC near-field communication device generates a modulated signal, it may adopt an active load modulation (Active Load Modulation, ALM) or a passive load modulation (Passive Load Modulation, PLM) manner. [0003] Currently, the NFC device can judge whether to use the ALM or the PLM...
