AI Technical Summary
Technical Problem
When a mobile phone is used as a card reader, the success rate of reading NFC tag information in low-power card detection mode is low, which affects the user experience.
Method used
By detecting the detection signal status of the card reader through near-field communication equipment, and transmitting a disturbance signal that interferes with and superimposes with the detection signal, the card reader is prompted to exit the low-power card detection mode, thereby improving the card reading success rate.
Benefits of technology
It improves the card reading success rate of different mobile phone models in low-power card detection mode, thus enhancing the user experience.

Abstract
本说明书一个或多个实施例提供了一种近场通信方法及设备。近场通信设备可以检测读卡设备在低功耗卡片检测模式下发射的探测信号；在检测到第一探测信号的传输状态满足干涉叠加信号的条件的情况下，发射扰动信号，以使扰动信号能够与第一探测信号干涉叠加后促使读卡设备退出低功耗卡片检测模式。
