Can I take the subway if my health code is abnormal?

In order to prevent and control the epidemic accurately, everyone who enters the subway station must scan the code to reflect the status of their health code in real time and effectively, and record the arrival of passengers. The staff will confirm according to the time and place when the green pass certificate is generated after scanning the code.

Special reminder: Please don't scan the code if you don't actually enter the subway station. Random code scanning may affect the results of epidemic investigation.

How do old people, children and others who can't use smart phones check the code? For the elderly, children and other people who can't use smart phones, the subway still uses staff to assist in card inspection.
