Captured screen images of the bill payment task on the K-mobile banking PLUS
application
they then concomitantly find the application is very convenient. Users also consid-
ered the user interface of the application, since a good design can allow them to be
clearer in using the application and finish their tasks very quickly. Although the
K-Mobile Banking PLUS application has a nice and consistent layout, most of
participants who performed the bill payment task were confused about the menus
because the location of its menu is different from the location on the ATM
(Fig.
10.9
).
The last factor was the service quality where some participants who failed to
operate the application correctly then lost their trust of the application. In effect
they perceived their errors as application errors and so the application becomes
perceived by them as unreliable and untrustable.
10.3.2.2 Result from Compared Means
The results of compared means analysis are described for the difference between
two groups. The point that we are interested is the potential significance of the
participant's prior experience on using a touch screen mobile phone towards the
ease of use and the intention to use. The results are shown in Tables
