The list of advantages and disadvantage of the mPay application
Advantages
Disadvantages
1. Application screen is graphic-based
1. The icons don't allow the user to
immediately identify their function
2. Application form uses icon images with an
underlying description
2. The graphic-based screen takes longer
to load than a text-based one
3. Has full functionality in terms of paying for utilities
and entertainment
3. Have to connect to the internet
4. Makes daily life easier and more convenient
4. Cannot customize icons for other users
5. Screen by the icon organizes the work into easy to
use categories
5. Fee for service is more expensive than
other applications
6. Frequently used functions can be added to the
favorite menu, which makes management of
applications consistent with the individual
6. Can only be used through the AIS,
GSM and 1-2-call networks
7. Good response time and a clear status indication
while the transaction is underway
7. Must have a mCASH account
8. Registration is difficult and each bank
has a different system
does not have any effect on the ease of use for mobile payment applications agrees
with the participants who said that both the K-Mobile Banking PLUS and the mPay
applications have transaction tasks that are useful and easy to use.
(b) Is prior experience on using a touch screen mobile phone significant in deter-
mining the intention to use?

The average intention to use for people who have prior experi-
ence on using a touch screen system on a mobile phone.

Assumed that:
1. Dependent variable “intention to use” is a numerical variable.
2. The dependent variable is normally distributed.
3. The two groups have approximately equal variance on the dependent variable.
The independent samples t-test was used because it tests whether the means of
two groups (experienced and non-experienced groups) are equal or not, and the
means in this test are numerical variables (intention to use).
In Table
10.7
, the Levene's test for equality of variances showed that the F ratio
(0.327) is not significant (p
0.569), and so the two variances are not significantly
different. Thus, equal variance was assumed with a t value of 0.480 and 98 degrees
of freedom. The obtained p value (0.632) is not greater than the 95 % confidence
