Problems solved by technology

Because the communication distance of the uncalibrated RF SIM card is far or near, the general calibration system generally cannot automatically judge whether the RF SIM card accessed through wireless means really needs to be calibrated, which is likely to cause miscalibration problems

Embodiment Construction

[0027] The main idea of ​​the present invention is to determine the attenuation parameter of the RF SIM card by scanning the multiple distances of the RF SIM card and multiple angles at the distance, and write the attenuation parameters into the RF SIM card . It is used to control the swiping distance during the mobile payment process. And through the way of service code verification to solve the problem of misalignment and interference between multiple SIM cards during the calibration process of radio frequency SIM cards.

[0028] The principles and features of the present invention will be described below with reference to the accompanying drawings and embodiments. The examples cited are only used to explain the present invention, not to limit the scope of the present invention.

[0029] Based on the concept of the present invention, the radio frequency SIM card that can be calibrated by the present invention needs to have a verification function. Here, we will introduce the str...

Abstract

The invention relates to a system for calibrating a radio frequency subscriber identity module (SIM) card, which includes an information input and output device, a radio frequency (RF) receiving and transmitting and detecting device, a controller, a serial port updating device, a machine lifting device and a machine rotating device, wherein the information input and output device, the serial port updating device, the RF receiving and transmitting and detecting device, the machine lifting device and the machine rotating device are respectively connected to the controller, and the machine lifting device and the machine rotating device are respectively connected to the RF receiving and transmitting and detecting device. The system for calibrating the radio frequency SIM card can automatically judge whether the radio frequency SIM card which is wirelessly accessed is needed to calibrate, thereby avoiding the problem of mal-calibration.

Description

Technical field [0001] The invention relates to the field of radio frequency communication, in particular to a method and system for calibrating a radio frequency SIM card. Background technique [0002] The SIM (Subscriber Identity Model, Subscriber Identity Model) card of the existing mobile communication technology is widely used in mobile communication terminals (such as mobile phones). With the development of science and technology, various smart circuit modules are added to the SIM card body of ordinary mobile communication terminals through various methods, so that the SIM card has not only basic SIM card functions, but also other functions closer to life. RF SIM card is one of them. The radio frequency SIM card uses active radio frequency technology to enable ordinary SIM cards to have mobile payment functions such as electronic wallets, or consumer applications such as access control. Among them, the short-distance solution for mobile communication terminals based on th...
