Formulation of the problem

The task is to design and implement a web-based system that governs the process of payment and access control for a network of sports facilities. A client of the facilities uses PayPal to pay his monthly subscription or a predefined number of practices, and is issued an RFID card that can be used to verify his legitimacy to access the facilities. The system should also keep track of his payment and attendance histories.

Architecture

Client-server MVC (Model View Controller) application using external services (PayPal API for payment processing, Yahoo! Finance Info for the currency exchange Rates, etc). As an extra to the classical 3-layer model are employed a Data Layer and an ORM models.
