project is implemented for. So, if the reader will read this document he will
get the clear idea about the system, what are the functionalities and features of
the system.

2.1.3. Project Scope and
Product Features

The system will run
and manage the cafeteria business systematically. In UOG smart café system, we
will provide a mobile application that can be used by the users to place their
order. So, the owner of the cafeteria can evaluate the system and maintain proper
check and balance. This will lead the owner to hire less no. of waiters and
create an opportunity to provide a better place for customers and appoint more
chefs. The customers can also make payment through their accounts which they opened
