Zebra MK3100 was a compact micro kiosk designed to support self-service and employee-assisted applications in retail environments. Featuring a color touchscreen, integrated barcode scanner, and wired or wireless connectivity, it enabled price checks, product lookups, and task management at the aisle level. Although discontinued, the MK3100 is recognized for its small footprint, easy integration, and role in advancing in-store automation. Zebra now recommends the CC600/CC6000 series as modern alternatives.
