Abstract - Religious institutions such as Hindu temples receive millions of devotees annually, yet the operational infrastructure supporting prasadam distribution, darshan scheduling, and visitor management remains largely manual and paper-driven. This results in severe crowd congestion, excessively long queues, lack of real-time information, and significant accessibility challenges for elderly and differently-abled pilgrims. The present paper proposes a QR-Based Digital Prasadam Booking System designed to modernize and streamline the temple visitor experience through the integration of contemporary web technologies. The proposed system leverages React.js for the frontend interface, Firebase Authentication for secure user identity management, Firestore as a scalable NoSQL database for booking and inventory records, and the Razorpay payment gateway for seamless digital transactions. Visitors can initiate the booking process by scanning a QR code placed at the temple premises, select their preferred prasadam type and quantity, complete payment online, and receive a unique digital booking confirmation QR code for staff verification at the counter. The system supports both guest access and Google-authenticated user accounts, ensuring broad accessibility. Empirical evaluation demonstrates significant improvements in operational efficiency, reduction in waiting time, and enhanced usability across diverse visitor demographics.

1. INTRODUCTION

Temples and religious institutions across India and Southeast Asia serve as major pilgrimage destinations, drawing millions of visitors each year. These institutions are deeply embedded in the social and cultural fabric of communities, providing spiritual services, distributing sacred food offerings (prasadam), and facilitating ritual worship. Despite their cultural prominence, the operational mechanisms underlying temple management remain heavilydependentonmanualprocesses,paper-basedsystems,andin-personqueuing.Theconvergenceofincreasing visitornumbersandinadequatedigitalinfrastructurehascreatedpersistentchallengesthatunderminethequalityof thedevoteeexperienceandstraintempleadministration.

2. REVIEW OF LITERATURE

Sapna Rangari, Anshul Thakre, Aniket Potbhare, Shreyash Gajbhiye, Prince Wasnik [1] presented an analysis of QR code applications in online reservation systems, highlighting their effectiveness in improving efficiency and user convenience across domains such as ticket booking and event management. Punyaslok Sarkar and Sherly Noel [2] developed an online ticket booking system incorporating user authentication, secure payment processing, and QRbased validation, demonstrating reduced manual workload and improved user satisfaction. Ranjana Singh et al. [3] proposed a cloud-based ticket booking system that enables real-time updates and eliminates the need for physical ticketcounters,therebyenhancingaccessibilityandconvenience.P.Sureshand

B. Muni Archana [4] designed an online light booking system that provides centralized access to light information, improvinguserdecision-makingandbookingefficiency.

Further studies [5]–[12] explore digital ticketing systems, blockchain-based ticket validation, and decentralized booking platforms, emphasizing enhanced security, transparency, and fraud prevention. These works demonstrate howmoderntechnologiescanimprovetrust,scalability,andefficiencyinbookingsystemsacrossvariousdomains.

Recent works [13]–[20] focus on QR code-based ticketing systems and Firebase-based real-time applications, demonstrating improved validation speed, prevention of duplicate usage, and enhanced system scalability. These studies collectively highlight the effectiveness of digital booking systems in reducing manual effort, improving user experience, and ensuring secure and efficient transaction management. However, limited research has been specifically focused on temple management systems, particularly prasadam booking, which motivates the developmentoftheproposedQR-BasedDigitalPrasadamBookingSystem.
