Service Representative Functions: Door Operations and Price Selection

The Service Representative (SR) manages door locking, unlocks, history display, and price selections. The SR interacts with the MIVM software to change modes, display history, total income, and total items sold. Using buttons and switches, the SR makes item selections, invokes changes, and resets modes. Customer interactions involve item dispensing, refunds, and credit management. Coordination packages ensure smooth operations.
