Treffer: Innovation without Limits: A Disciplined and Accessible Model for Sustainable Technological Development.

This paper presents a lightweight software architecture that integrates embedded Near Field Communication (NFC) technology into wearable systems for real-time traceability and operational automation. The proposed model was developed within a resource-constrained context and applied across multiple domains, specifically healthcare, education, and tourism, where infrastructure and connectivity are often limited. The system architecture is based on five key principles: modular design, disciplined development, goal-oriented execution, iterative improvement, and ethical software engineering. These principles support the deployment of low-cost embedded systems that function without continuous internet access, making them suitable for underserved environments. Through empirical evaluation, the model was benchmarked against traditional software solutions in each sector. Results indicate improvements in process efficiency (e.g., faster identification and tracking), significant cost savings, and enhanced user experience. For example, in clinical settings, the use of NFC-embedded garments led to a 35% increase in equipment traceability and a 40% reduction in identification errors. The contribution of this study lies in demonstrating that disciplined, purpose-driven software engineering can yield effective embedded systems without relying on advanced infrastructure. The model provides a replicable framework for developers seeking to implement frugal yet functional systems across diverse, real-world environments. [ABSTRACT FROM AUTHOR]
