Nanchang Gantong Code is a digital platform for epidemic prevention and control built by Nanchang. Citizens can pass through public places in Nanchang with the long pass code. At present, according to the work requirements of Nanchang Emergency Prevention and Control Front Headquarters, citizens need to show health codes, nucleic acid test reports and other epidemic prevention information when entering and leaving various public places. A unified interface that can display all the contents that need to be checked is very necessary to improve the efficiency of prevention and control and save the travel time of citizens.
