Develop a simplified queue management system to effectively manage customers’ waiting time in cellular retail stores. Design must consider various device aspect ratios.

THE SYSTEM INCLUDES 3 DISPLAYS:
Display 1: Customer iPad screen cycles messages until customer initiates interaction. Upon touch, customer interface screen appears. Once completed, a ‘Thank You’ message confirms completed form. Message displays for a few seconds then resets to 3 cycles messages.
Display 2: Store employee facing screen interface. Employee can que up names and edit featured promotions.
Display 3: Customer facing screen - large monitor - presents the current que of customers.

TEXT CAN ALLOW DIFFERENT MESSAGES BASED ON ENTITY. CLOSE SCREEN RESETS TO ‘START’ STAGE IN ROTATION SERIES. IF NOT CLICKED, THE SCREEN WILL AUTO RESET AFTER A SPECIFIC DURATION.
