Description

technical field [0001] The invention relates to the technical field of magnetic communication, in particular to a magnetostatic communication system and a method thereof. Background technique [0002] Smartphones and wearable devices are becoming more and more common, and conventional data interaction methods have achieved relatively advanced development, such as WIFI, Bluetooth, QR codes, NFC, etc. However, some applications require short-distance communication, such as near-field payment, short-distance card swiping, short-distance information transmission, etc., all require short-distance communication. Existing near-field communication methods include NFC, scanning QR codes, etc., all of which have certain problems. The renovation cost of NFC payment facilities is high, and the compatibility is poor; to scan a QR code, you need to turn on the camera of your mobile phone and point it at the QR code to scan, which is slow. Therefore, it is cumbersome in some application ...
