I need an SRS document

Prepare a Software Requirement Specification (SRS) for a Cashless Ticketing System. It is recommended that you use a SRS template that is organised by features, i.e. List the features and their corresponding functional requirements. You also need to consider performance requirements, design constraints, and other relevant requirements.
The SRS will also need to include the use of appropriate diagrams to complement the SRS as well as relevant references (in Harvard format)
