 2 weeks: Design and Core Features
 5 weeks: Testing and Additional Features
 Spiral model
 Prototype
 Beta
 Release
 Each feature is an independent task

9. Feasibility Rationale
 Emulation of cash registers
 Trusting SSL for encryption
 Loss of connection to server
 Relies on following a restocking procedure
 Theft breaks synchronization between the
