Integrated design ID adopted, card inserting place and battery are equipped right ahead of the meter so that they are easy to be installed and used;
The company uses international advanced MSP430 chips of American T COMPANY, which are featured with low power consumption, high capacity, strong intelligence, stable performance, programs can be erased and updated repeatedly;

American Atmel1608 logic encrypt card is used for IC card, Atmel1608 card has huge memory, strong confidentiality and attack tolerant performance, reading and writing of the information in cards employs double encryption;
The function of two-way information transmission: The gas company uses management system and IC card to transmit the related data (such as gas capacity, idle time upper limit of meter storage capacity, low alarm limit, overload limit, ect. ) to the controller inside meter, which can control the usage of meters according to the parameters uploaded IC card. Meanwhile, the data on the meter (such as using data of meter, attacking and faults of customers) will also be transmitted to the system through IC card so that the gas company can analyze the customers according to the returned customer data;
