The study of trust of consumer on Business-to-Consumer (B2C) E-commerce is one of the key research interests of Information Systems (IS) researchers. In this research, we investigate the impact of trust on two different E-payment gateways, viz. online credit card payment system and the hypothetical online Octopus card (a stored-value smart card) payment system. Based on the model developed by G...

Conventional credit card transactions are not consistent with Islamic principles, as exemplified by the Islamic banking system and the ‘Murabaha sale’. On the other hand, EMV-compliant IC (Integrated Circuit) cards have been developed to secure traditional Point of Sale (POS) transactions. Thus, if Islamic principles are to be applied to card payments, a new and secure card payment process is r...

This paper provides a new theory for two-sided payment card markets by positing better microfoundations. Adopting payment cards by consumers and merchants requires a fixed cost, but yields lower marginal costs of making payments. Considering this together with the heterogeneity of consumer income and merchant size, our theory derives card adoption and usage pattern consistent with cross-section...

Then consider the case of Sofortüberweisung, a controversial entrant to the payment market in Germany. Its name means “instant payment,” and its service has taken off rapidly in the past 2-3 years. Branded as Sofort (Instant), this service provides merchants with a low-cost payment service for online shopping. It is promoted by some large sites (such as airlines) by exempting users from the sur...

Mobile wallets promise to allow people to easily manage their accounts and to carry less cards. However, the slow adoption of contactless point of sales (POS) terminals by merchants limits the potential of Near-Field Communication (NFC) based payment devices. In this paper, we discuss Wild Card, a secure and backward compatible way to make mobile payment through conventional magnetic stripe bas...

Payment cards offer a simple and convenient method for making purchases. Owing to the increase in usage of payment cards, especially online purchases, fraud cases are on rise. The rise creates financial risk uncertainty, as commercial sector, it incurs billions losses each year. However, real transaction records that can facilitate development effective predictive models detection difficult obt...

classes Following object-oriented principles, a class that cannot be instantiated is said to be abstract. Abstract classes are often used for grouping together the common elements of a set of specialized classes. Example: Payment Cash Payment Credit Card Payment Check Payment amount: int The name in italics indicates an abstract class.

Many security protocols rely on authentication of communicating entities and encryption of exchanged data. Traditionally, authentication and encryption have been separate processes, however there are combined solutions, referred to as authenticated-encryption (AE). The payment card industry is revising its protocol specifications and considering AE, however there has been uncertainty around per...

Credit cards and the subsequent payment of credit card debt play a crucial role in e-commerce transactions. While website design effects on trust and e-commerce have been studied, these are usually coarse grained models. A more individualized approach to utilization of online credit card payment services is examined that utilizes personality as measured by the Myers-Briggs personality type asse...
