RADIO FREQUENCY SENSITIVEITY REVISION METHOD AND THE DEVICE OF RADIO FREQUENCY CARD TERMINAL

摘要

A method and a device for correcting RF(Radio Frequency) sensitivity of an RF card terminal are provided to correct an RF sensitivity value of the RF card terminal to the optimal RF sensitivity value by using an installation place of the RF card terminal and basic information of the RF card. A first memory(20) stores information for success/failure and an RF sensitivity value when an RF card(200) is interlocked with an RF card terminal(100). A second memory(40) stores RF card information, a setting value for installation environment information of the RF card terminal, and a preset RF sensitivity point. An RF sensitivity setting part(30) corrects the RF sensitivity value to the optimal RF sensitivity value by analyzing the success/failure information stored in the first memory, extracting the preset RF sensitivity point in reference to the RF card information and the installation environment information stored in the second memory, and applying the RF sensitivity value of the extracted RF sensitivity point to an RF antenna(50). A login manager(10) stores the success/failure information when the RF card is interlocked with the RF card terminal. A main memory(60) stores an operating software of the RF card terminal to load the first and the second memory.
