Self-Service Information Kiosk for Public Tax Payments
Eastern Europe | Industrial Design, Hardware Integration & Production Supervision
This hardware integration case study documents the engineering process, component matching, and supervised production of a public self-service payment kiosk.
Project Overview
Project G639 was developed for a Romanian IT company operating across Eastern Europe, specialized in software solutions for public administration and digital public services.
The client had completed the software platform for a self-service tax payment system intended for public environments. The project required a complete hardware ecosystem capable of supporting continuous operation, secure transactions, and scalable deployment.
SHAMANA was engaged to convert functional software requirements into a fully engineered, manufacturable, and deployable hardware system, while acting as the technical owner of the hardware process on behalf of the client.
Initial Client Input
The client provided:
functional requirements derived from the software architecture,
required user interactions and peripherals,
strict maximum external dimensions,
no industrial design,
no validated hardware architecture,
no production or quality control framework.
The challenge was not procurement, but end-to-end hardware engineering and execution control.
SHAMANA Scope of Work
SHAMANA assumed responsibility for the complete hardware lifecycle:
industrial design and hardware architecture,
component matching and technical validation,
factory selection and integration setup,
production supervision and quality control,
technical documentation,
deployment and commissioning readiness.
Industrial Design & Hardware Architecture
SHAMANA defined the complete physical and technical architecture of the kiosk, translating abstract functional requirements into a coherent industrial product.
This included:
enclosure proportions and structural logic,
internal component layout and access paths,
thermal and electrical design constraints,
reinforcement for public-use environments,
compliance with all dimensional limits.
The result was a repeatable, serviceable industrial design, not a one-off prototype.
Custom Display & Touch Integration
To meet usability requirements, SHAMANA engineered a custom large-format interface:
32-inch industrial display,
customized projected capacitive touchscreen (CTP).
The integration required mechanical adaptation, precise alignment, signal compatibility validation, and long-term reliability assurance within the kiosk architecture.
System-Level Component Matching – Hardware Integration Case Study
Project G639 was engineered at system level, not component level.
The kiosk integrates:
industrial embedded PC,
32” custom display + CTP,
camera-based QR / barcode scanner,
thermal receipt printer,
Wi-Fi connectivity,
5G cellular connectivity for autonomous and redundant operation,
power conversion and internal cabling systems.
All components were selected and matched based on compatibility, reliability, serviceability, and lifecycle availability.
Connectivity & Computing Architecture
The system core is an industrial-grade computing platform designed for continuous operation.
Dual connectivity was implemented:
Wi-Fi for local network environments,
5G for independent operation and redundancy in public infrastructure deployments.
This architecture ensures operational continuity and flexible installation scenarios.
Factory Selection & Production Supervision
SHAMANA identified and coordinated a factory capable of full system integration.
Beyond design transfer, SHAMANA actively supervised the production process on behalf of the client, ensuring:
correct implementation of the approved design,
compliance with integration and assembly instructions,
consistency across all produced units,
early detection and correction of potential deviations.
Production supervision was performed as a technical control function, not as product ownership, ensuring the client received hardware aligned with the validated specifications.
Manufacturing Instructions & Factory Enablement
To support controlled production, SHAMANA developed a factory-specific assembly and installation manual, including:
step-by-step assembly instructions,
wiring and interconnection logic,
critical inspection checkpoints,
validated installation sequences.
This documentation enabled the factory to reproduce the system reliably and consistently.
Operation, Commissioning & Usage Documentation
SHAMANA also prepared:
an operation manual,
a commissioning and initial setup guide,
usage instructions adapted to public-service environments.
These documents ensure independent installation, commissioning, operation, and servicing of the kiosks.
Production & Deployment Status
The system was approved after prototype and validation phases.
Project G639 entered series production.
Approximately 80–100 units are currently deployed.
The kiosks are actively used for public tax payment services.
Technical Outcome
Through industrial design ownership, system-level engineering, production supervision, and comprehensive documentation, Project G639 evolved from a software-only concept into a stable, scalable public-service hardware platform.
The project demonstrates SHAMANA’s ability to:
engineer industrial hardware from functional requirements,
integrate complex multi-component systems,
supervise production on behalf of clients,
deliver deployable, service-ready hardware solutions.
Final Takeaway
Hardware integration does not end at design approval.It ends when production consistently delivers what was engineered.
