Being one of the largest networks of ticketing systems operating over 1,015,000 km and transporting over 22 million visitors daily, e-ticketing systems spend over CR 94,000 to operate efficiently. From the recent proposal for smart cities, ticketing systems are projecting to museums and cultural monuments with the current trend towards digitization, smart ticketing systems are the most of the hour. Of the 94,000 kr. is an exorbitant salary of 23,500 kr. spent on paper that can be subsidized using effective alternative techniques. The smartphone, which has a profound effect on people's daily routine, can be used for paperless ticketing. In today's digital era, the way we access and experience cultural heritage sites, such as museums and monuments, is evolving. Traditional paper tickets and long queues are fast becoming outdated, replaced by more efficient and user-friendly digital solutions. This project explores the development of a Mobile based ticketing system that simplifies the ticket purchase process for visitors, provides easy entry verification through QR codes, and enhances security with biometric authentication. Beyond improving the visitor experience, this system helps site administrators manage visitor flow, protect against fraud, and even reduce environmental impact by going paperless. The application’s aim is to create a seamless and enjoyable journey for visitors—from purchasing tickets to entering the site—while providing insightful data for site managers on visitor patterns and peak hours. This digital transformation reflects the larger trend of integrating technology into our everyday experiences, making heritage sites more accessible, sustainable, and enjoyable for everyone.
