Public transportation systems face rising pressure to provide services that are secure, efficient, and accessible to users, while still having a major segment dependent on outdated infrastructure which cannot fulfill the demands of modern-day commuters. Some key challenges include inefficient fare-collection mechanisms, rigid travel routes and poor provision of real-time information. This paper covers the adoption of Radio Frequency Identification (RFID) and Near Field Communication (NFC) technologies within the public transportation system as one of the comprehensive approaches. The proposed solution integrates safe and contactless fare collection along with dynamic travel flexibility through real-time GPS updates with help of smart cards as well as mobile applications. Its multi-phase research approach toward requirement analysis, prototype building, pilot testing, and scaling up ensures the robustness as well as practicality in the system. Modular architectures for scalability, safe use of advanced encryption, as well as intuitive interfaces towards users are integrated into this proposed solution. Pilot implementations show considerable improvements in operational efficiency, transaction accuracy, passenger satisfaction, and system reliability. The results show that RFID and NFC technologies are promising innovations to transform public transportation to address essential weaknesses in security, adaptability, and user convenience. This work lays a foundation for introducing innovative, integrated solutions to urban mobility in a manner that promotes sustainable, adaptable, and commuter-centered transit systems.
