Proprietary Hardware Costs
Commercial systems with specialized devices can carry high procurement and maintenance costs for regional government needs.
Queue System &
IoT Integration
A Queue Calling System that connects touchscreen kiosks, queue displays, counter call devices, and a management dashboard in one real-time flow. Hardware and software are designed together to be adaptable to public service needs with different counter and service category configurations.

About QCS
QCS was developed for queue management in public service environments that require a more flexible system than proprietary queue machines. Each implementation can adjust service categories, number of counters, agency identity, and the devices used at the location.
Usage ContextPublic Service with Multiple CountersUsed in environments with multiple service types, staff, and different counter configurations.
System ApproachIntegrated Hardware & SoftwarePhysical devices in the field are designed as part of the application flow, not as standalone components.

Operational Challenges
A queue system for public services needs to remain easy for visitors to understand, simple for staff, and flexible enough for various agency configurations. Rigid proprietary solutions can also make hardware costs and vendor dependency significantly higher.
02
Queue Status Not Clearly Visible
Without a continuously updated display, visitors struggle to understand which number is being called and which counter is serving.
03
Devices Difficult to Reuse
Vendor lock-in can restrict the use of monitors, printers, or common devices when system configuration changes.
04
Each Agency Has Different Configurations
The number of counters, service types, tenants, branding, and supervision needs differ at each implementation location.
The Solution We Built
Solunesia developed QCS from the device layer to the application. Touchscreens at the entrance, counter call devices at each counter, public displays, and the management dashboard all operate on the same queue state so changes are instantly visible at every point.
Implementation Approach
Use standard devices, then control the experience through software.
Microcontroller-based devices are used on the counter side and connected to the staff workstation. Displays can use standard TVs or monitors, while real-time communication keeps queue changes synchronized without requiring proprietary devices at every point.
Core principleHardware stays simple and maintainable, while queue rules and service configuration are managed through the system.
Touchscreen for Number Taking
Visitors select a service category from the kiosk and receive a queue number based on the available services.
IoT Device at Each Counter
Staff can call the next number, recall, or go back to the previous number from a physical device.
Real-Time Public Display
A TV or monitor shows queue numbers and active counters based on changes received in real time.
Dashboard for Supervision
Supervisors can view counter status, open or close services, and manage operational configuration.
Devices & Integration
Four core components work as one system. Visitor-side and staff-side devices are built to follow the same operational flow as the displays and dashboard.
01
Touchscreen Kiosk
The kiosk is placed at the entrance and displays available service categories. Each implementation can have more than 12 service categories and different tenant branding.
Service types can be configured per location.
Service buttons can be disabled when a service is closed.
Tenant identity and logo can be customized.
02
Queue Display
The public display shows the relationship between queue numbers and the counter currently serving. Changes are sent in real time and can be shown on a connected TV or monitor.
Supports displaying multiple counters on one screen.
Queue status history remains visible to help visitor orientation.
Can use standard HDMI TVs or monitors.
03
Counter Call Device
A microcontroller-based device is placed on the staff desk and connected via USB to the workstation. Physical controls are kept simple so staff do not need to switch applications for basic calling functions.
NextCall the next queue
PreviousGo back to previous number
RecallRecall the active number
Real-Time Synchronization
Every queue change runs through the same state. Number taking, counter calling, and display updates are not processed as separate systems.

Field Implementations
QCS configuration is tailored to each agency's needs. Differences in counter count, service categories, tenants, and visitor characteristics are not forced into one identical configuration.

Implementation Impact
The integration of devices and applications makes the queue flow easier to monitor for both visitors and staff. The system can also be deployed across multiple types of agencies without depending on one proprietary hardware configuration.
✓
Clearer Queues for Visitors
Active numbers and serving counters are visible on a continuously updated display.
✓
Standard Devices Can Be Used
TVs, monitors, workstations, and microcontroller-based devices can be combined as needed per location.
✓
Configurable to Requirements
Service categories, tenants, branding, and counter assignments can differ at each implementation.
✓
Hardware & Software as One System
Actions from the kiosk and counters are instantly reflected in the queue state and public displays.
Share Your Current Service Flow
Start with the number of services, counters, queue patterns, existing devices, and visitor issues in the waiting area.
Map Devices & Integration
We help define the roles of kiosks, displays, counter devices, local networks, and the dashboard that are actually needed.
Define the Scope
Once the operational flow is clear, hardware configuration, software, and implementation phases can be structured more effectively.
