As the opportunities offered, most individuals and businesses feel that E-banking energies are great. Thus, threats are unavoidable to banks if they fail to identify consequences and vulnerabilities accompanying e-banking practices. The usage rate of e-banking in a top international commercial bank in Malaysia is rather diminutive compare to its other bases in countries like Singapore, China and India. Interestingly, it is on decreasing mode year by year. This study aimed to offer a good set of information of the factors influencing low usage and possibilities to suggest ways to increase the usage among the bank customers. In this study, a comprehensive survey data gathering were used to collect and analyze the respondents and results indicate that ease of use is the most significant contributor to the low usage. 204 valid feedbacks were obtained from the SCM bank's customers, with the research indicating that e-banking still has a gap to fill between customers, the bank and the e-system in maximizing the desire of existing clients to go over the net. 展开更多

This article aims at characterization and assessment of the financial behaviors of rural dwellers on non-cash payment markets and identification of factors determining the intensity of using individual methods of payment by the inhabitants of rural areas. The main source of data used for analysis and inference was information originating from the authors' own investigations conducted in 2013 on a group of 500 rural households and on a group of 150 trade and service points operating in non-urbanized areas. This work made use of statistical summary measures and Z2 independence test. According to the results of the conducted studies, forms of payment used by rural dwellers depend on many variables, of demographic, economic, and psychological character. Cash payments are more frequently used by persons possessing vocational or secondary education, elderly people, old-age pensioners, annuitants, or households with lower incomes. Also, persons who do not trust financial institutions or do not perceive benefits resulting from the use of non-cash instruments prefer cash. It is a group of households which require urgent educational activities in the area of non-cash payment instruments. A significant barrier to using non-cash payment instruments by rural dwellers was a limited access to non-cash channels. It is connected in the first place with a poorer development of financial infrastructure in rural areas (banks or cash points), insufficient Internet access conditioning a possibility to use electronic banking points, and also a worse development of credit card acceptance network. As has been demonstrated by the results of conducted studies, the main reason for a lack of point of sale (POS) terminals in retail and service-providing points operating in rural areas, in the opinion of their owners, is the very high interchange fee (50% indications), which under Polish conditions is one of the highest in the European Union (EU). 展开更多

In recent years, the development of electronic commerce has led to the creation of many new and interesting business models for intemet-based buying, and online group-buying has become an effective form of it. Online group-buying is a model in which consumers collaborate and purchase a good at a discounted price. The purpose of this study is to examine the effect of reputation, price and service on purchasing intention through mediator which is perceived risk. To empirically test the proposed model, a survey was conducted and 140 samples were collected. The result of this study shows price has a significant effect on purchasing intention through perceived risk. This result also shows service and reputation have an insignificant relationship with perceived risk. Therefore, online group-buying retailers should not only focus on making money from the business but also consider how to keep consumers for future business. 展开更多
