New description: [New technology field] This new type relates to the field of communication technology, especially to the non-contact IC card dual-frequency card reading device with mobile phone card swipe distance detection function. [Prior Art] With the rapid development of China's national thieves, the people's living standards have been greatly improved, especially the rapid development of mobile communication technology and the development of the age-related market, and the increasing number of hand-lying functions is no longer limited to making calls. And the sending and receiving of short messages, which makes the application of mobile phones quite popular, mobile phones have become an indispensable necessity in people's daily life - a must-have item. It is precisely because of this increasing role of mobile phones that mobile phones have emerged as a means of mobile payment. From the perspective of security considerations, mobile payment for mobile phones requires proper control of the card's swipe distance. This distance is usually required to be within 5αη, and the excessive swipe distance is easily stolen or misapplied. The use of a mobile phone face card is a relatively effective technical means of the scale hand _ card. However, due to the directionality of the RF signal, the work is small, the sensitivity is accepted, it is difficult to accurately control, and it is necessary to detect and control it accurately. The card swipe distance has always been a problem. This has affected the promotion of mobile payment with mobile phones with mobile phone RF cards. [New content] The purpose of the new model is to overcome the prior art, and to provide a kind of mobile phone swipe distance M408081

The mobile phone RF card is to transmit the radio frequency signal, therefore, the distance control must be carried out; the 2.4g mobile phone RF card is not guilty When the card reading device is in the induction coil circuit 1 The coil should always be energized by a high frequency (i.e., 13 56M) alternating current excitation signal applied by the 13.56M • contactless card reader control circuit 2, which causes the induction coil to form a periphery at its periphery. The sinusoidal alternating magnetic field, the induction coil circuit 1 outputs a voltage signal to the rectifying circuit 3; when the 2 4G mobile phone radio frequency card is close to the card reading device, the metal material of the mobile phone itself generates eddy current due to the sinusoidal alternating magnetic field, The eddy current generates a new alternating magnetic field, which causes the impedance of the induction coil of the induction coil circuit i to change. The induction coil circuit 1 outputs a varying voltage signal to the rectifier circuit 3, the changed voltage signal. Corresponding to the distance between the mobile phone and the card reading device, the distance between the mobile phone and the card reading device can be obtained by detecting the voltage value; the voltage signal read by the rectifying circuit 3 is rectified and becomes a constant current signal. The DC signal is connected to the A/D conversion interface of the first M408081 4G RF transceiver driver 2.4G RF transceiver driver circuit 5, which is performed by the first 2. A/D conversion, the converted data is rotated by the first 2. 4G radio frequency blowing drive circuit 5 to the main CPU circuit 9; the main CPU circuit 9 analyzes, calculates and processes the data, and further to the first 2_4G surface The transceiver driving circuit 5 outputs a control signal, and the first 2.4G radio frequency transceiver driving circuit $ controls the attenuation degree of the radio frequency signal through the programmable attenuation circuit 6, thereby realizing the 1-2th radio frequency transceiving driving circuit 5 through the first-radio antennas 4 and 2.
