Description

technical field [0001] The invention relates to the technical field of mobile phones, which can enable the mobile phone to have NFC (Near Field Communication) function, and at the same time have very low implementation cost and do not need to carry out hardware transformation on the SIM card, realize the communication between the NFC device and the SIM card and support NFC Power-down working mode, so that this type of mobile phone is widely used in contactless payment, access control, anti-counterfeiting and other application fields. Background technique [0002] After more than ten years of development, IC (Integrated Circuit) cards, especially non-contact IC (Integrated Circuit) cards, have penetrated into every corner of modern life and are widely used in public transportation, access control, and small-amount electronic payment. In recent years, driven by the needs of rail transit, logistics management, anti-counterfeiting, and identification, etc., the technology of non...
