Universal two-dimensional code verification method based on park system

The invention relates to the technical field of park management, in particular to a universal two-dimensional code verification method based on a park system, which comprises a property management terminal, a service terminal and a user terminal, and comprises the following specific steps: (1) a user performs two-dimensional code function operation of the user terminal and directly opens a universal two-dimensional code; (2) a user applies for a token from a server side through a user side, generates a dynamic secret key according to the token, and generates a two-dimensional code through thesecret key and a user identifier; (3) the user shows the two-dimensional code to a property management person, and the property management person uses the property management terminal to scan the two-dimensional code; (4) the property management terminal verifies the secret key of the user; (5) the property management terminal selects a processing service in the service list; and (6) the propertymanagement terminal comple
