Aim/PurposeThe aim of this study is to develop and evaluate the King’s Way Cashless Payment and Product Monitoring System with QR Technology, specifically designed for the fitness industry. The system seeks to enhance operational efficiency, strengthen transaction security, and provide a seamless experience for gym members and administrators through digital transformation. Its novelty lies in the integration of QR-based transactions with automated membership and product monitoring features within a unified platform, a combination not yet widely adopted in small and medium-sized fitness enterprises.

BackgroundWith the rapid rise of digital payment technologies, the shift toward cashless transactions has become indispensable for modern businesses. The fitness industry, characterized by frequent transactions and dynamic membership management, continues to struggle with inefficiencies caused by manual payment and record-keeping systems. These traditional processes are prone to delays, errors, and data security vulnerabilities, underscoring the need for an integrated digital solution tailored to the operational structure of fitness centers.

MethodologyThe system was developed using Agile methodology, allowing for iterative testing and user feedback integration throughout the development cycle. Functionalities include QR-based payment processing, automated membership tracking, and real-time sales monitoring. Usability and performance were assessed using the System Usability Scale (SUS) and time-efficiency metrics.

ContributionThis study provides a validated prototype that demonstrates the feasibility and effectiveness of integrating QR technology into gym operations. It distinguishes itself by combining cashless payment, membership management, and inventory tracking into a single, interactive system. The research also contributes empirical data on user acceptance and operational impact, offering a benchmark for future digitalization initiatives in the fitness sector.

FindingsPerformance evaluation revealed significant efficiency and accuracy improvements over manual systems, including the following:
80% reduction in average transaction time,
95% accuracy rate in financial and inventory tracking, and
88/100 mean SUS usability score.
Statistical analysis confirmed that the digital system significantly improved transaction speed, reduced administrative workload, and enhanced data security compared to traditional methods (p < 0.05).

Recommendations for PractitionersFitness centers and similar service-based enterprises are encouraged to adopt integrated digital systems combining payment, monitoring, and tracking features. Emphasizing real-time data visibility and user-friendly interfaces can lead to improved customer satisfaction, operational transparency, and streamlined business management.

Recommendation for ResearchersFuture researchers should explore cross-industry applications of QR-based management systems and analyze how demographic factors influence user adoption. Longitudinal studies are also recommended to assess the sustained effects of system implementation on business performance, customer loyalty, and profitability.

Impact on SocietyThe study supports the broader shift toward cashless, contactless payment solutions, promoting digital inclusion and operational transparency. By minimizing human error and physical cash handling, the system contributes to both public health safety and the digital advancement of small to medium enterprises in developing regions.

Future ResearchSubsequent system iterations will explore the integration of biometric authentication, AI-driven analytics for customer behavior insights, and multi-branch scalability. Further studies will assess user acceptance of these advanced features and their contribution to long-term business resilience and innovation in the fitness industry.
