This is a use case diagram for blockchain base RFID E-Voting System. A use case diagram can provide an overview of the users (sometimes referred to as actors) of your system and their interactions with it. You'll need a particular set of connectors and symbols to make one. Use cases describe the desired action (what), not the specific steps to make it happen (how). By describing all system behavior that is externally apparent, it is a useful strategy for explaining system behavior to users. EdrawMax lets you draw the use case diagram in a few simple steps.
