Conventionally, information and communication
technology (ICT) has been utilized to automate routine tasks in
business transactions such as customer registration system,
billing system, and inventory system. However, the evolution
of wireless technology and the emergence of mobile devices
have not only provided end users enjoyment in utilizing
automated systems but also new ways to communicate
information. In fact, the mobility and portability features of
mobile devices have drawn researchers to establish a
framework of mobile technology assessment in various ecommerce
applications [1].
The convergence of wireless and mobile technologies can
facilitate ubiquitous platform for implementing business
applications such as food ordering system. Without any
information and communication technology facilities, food
ordering procedures require waiters to note orders from
customers, bring orders to the kitchen, write receipts, and
deliver the ordered menu. Although such routines look simple,
the conventional food ordering system may significantly
increase the work load of waiters or even prone to human
errors in note making when the number of customers increases
during peak hours. Some preliminary efforts have been made to
