Introduction
In the context of e-commerce, salespeople are replaced
by a customer interface.
Consumer attitudes and beliefs about security have
significant effects on the intention to purchase online.
Few studies have examined whether customer interface
quality and perceived security affect customer satisfaction
and switching costs, and in turn, influence customer
loyalty.

Parasuraman et al. developed a scale with four dimensions (i.e.
efficiency of the website, system availability, privacy, and the
post-transaction experience).
Bauer et al. used five eTransQual dimensions
(functionality/design, enjoyment, process, reliability and
responsiveness).
This study primarily focused on the components of customer
interface quality that are related to online store atmospherics
rather than to the entire online buying experience.

Customer interface quality



This paper adopted four components of customer interface
quality that deal with its atmosphere:
 Convenience
 Interactivity
 Customization
 Character

Literature review(Cont.)
Perceived security


This paper defined perceived security as the extent to which a
potential customer believes that the e-commerce website is
secure for transmitting sensitive information.
Customer satisfaction


7
This paper treats customer satisfaction as a cumulative factor.

Literature review(Cont.)
Switching costs



Burnham et al. thought switching costs are not only economic
in nature, but can also be psychological and emotional.
This paper defined switching costs as the consumers
perceptions of the time, money, and effort associated with
changing e-service providers.
Customer loyalty


8
This paper defined customer loyalty as a customer’s favorable
attitude toward an e-commerce website that predisposes the
customer to repeat buying behavior.


Hypotheses development

Customer interface quality and perceived security
 Consumers may use interface quality as a surrogate indicator
when forming beliefs about security.
H1. Customer interface quality has a significant
positive influence on perceived security.

Research model and hypotheses
development(Cont.)

Hypotheses development

Customer interface quality, satisfaction and switching costs
 Customer satisfaction toward a website depends primarily on
the evaluation of its attributes.
 A good website avoids wasting customer time by providing
orderly screens, simple search paths, fast and readable
presentations, and simple navigation
H2. Customer interface quality has a significant
positive influence on customer satisfaction.
H3. Customer interface quality has a significant
positive influence on switching costs.

Hypotheses development

Perceived security, satisfaction and switching costs
 Consumers ' attitudes and beliefs about security have had
significant effect on their intention to purchase online.
 High switching costs are engendered when a customer
perceives one e-commerce website as being secure.
H4. Perceived security has a significant positive
influence on customer satisfaction.
H5. Perceived security has a significant positive
influence on switching costs.
