A system for security control and/or transportation of persons with an elevator installation and a method of operating this system. By means of the system, a person is identified from at least one identification code and from at least one authentication signal. For this purpose, an identification code is entered and/or transmitted by the person, and an authentication signal of the person is captured. Assigned to the identification code and the authentication signal is at least one user profile. An access authorization stored in the user profile, and/or a pre-defined travel destination in the user profile, is/are determined. The authentication signal is checked against at least one reference stored in a user profile. If an access authorization to a travel destination is present, and if the authentication signal and reference correspond, a command signal is transmitted to an elevator installation.
