Recently, the new function of "Healthy Ride Code" was launched on the Qingdao Metro App and Qindaotong App in Shandong Province. This function plays a positive role in "two codes in one", eliminating the need for passengers to switch back and forth between health code and ride code, making it convenient for citizens to "pass with one code".

The "Healthy Ride Code" is an upgrade of the original ride code. After the passenger completes the real-name authentication, the ride code will automatically display different colors according to the health code status, without the need for the user to operate again. Among them, the green "Healthy Ride Code" can be used for normal rides, while the yellow and red codes will not be able to be used for rides or to enter the station. This move will help further optimize the citizens' ride experience, improve traffic efficiency, and help promote the orderly advancement of epidemic prevention and control.
