Use Case Diagram for a Biometric System

Would anybody be able to outline how a use case diagram for a biometric system would look like? I am currently using Visual Paradigm but struggling in constructing the diagram because I am not sure how it should completely look. Any suggestions would be really helpful thanks.

Hello mvhart1,

I suggest you can reference to our courses in our online training center to learn about how to create use case model. We have both free and paid courses available. Feel free to contact me for any queries.

Best regards,
