The document describes a proposed mobile application for an electronic bus ticketing system. The proposed system would allow passengers to purchase tickets using a smartphone app and store tickets digitally. It would also allow ticket checkers to validate tickets digitally by searching the ticket number in a database. The system aims to address issues with the current manual ticketing system, such as time wasted purchasing paper tickets and the risk of losing tickets. It also outlines the design of the proposed system, including its system architecture, data flow diagram, and class diagram. The technical specifications, advantages, and limitations of the system are also discussed.
