Embodiment Construction

[0138] Let me first explain here that the terminal in this article below refers to a terminal equipped with a second radio frequency device by default, and refers to a terminal that can move, that is, a mobile terminal, such as a mobile phone, etc. The distance refers to the distance between the first radio frequency device and the second radio frequency device. The distance between the radio frequency devices, that is, the distance between the first radio frequency device and the terminal loaded with the second radio frequency device.

[0139] The present invention aims at the distance control problem between the second radio frequency device (especially the radio frequency card built in the terminal, such as the radio frequency SIM card) and the first radio frequency device to implement card swiping transactions, and proposes a signal transmission and reception function with a low frequency alternating magnetic field A communication system composed of a first radio frequency ...

Abstract

The present invention relates to a communication system and method, wherein the communication method of the present invention controls the communication distance between the first RF device and second RF device by low frequency alternating magnetic field, radio frequency channel by the first means and the second RF two RF devices to exchange information within a preset distance range.Communication system and method of the present invention provides the use of a low frequency alternating magnetic field of the communication distance detecting signal bidirectional effective control, thereby improving the communication distance problem of uncontrollable, improved communication security.

Description

technical field [0001] The present invention relates to the communication field, in particular to a communication system and method. Background technique [0002] With the popularization of mobile terminals, there is an urgent demand for mobile payment applications using mobile terminals. Currently, there are many implementation schemes, but each has its own disadvantages. At present, it has appeared in the mobile terminal SIM (Subscriber Identity Module) card, SD (Secure Digital Memory Card) card, Micro-SD card or mobile terminal motherboard, adding radio frequency functions, making the mobile terminal a recharge, consumption, transaction, A super intelligent terminal for identity authentication. In this solution, the radio frequency adopts UHF (Ultra High Frequency, ultra-high frequency) technology, so that after the radio frequency module is embedded in the mobile terminal, it can still be transmitted, so that the function of data communication can be completed without c...
