As Electronic Commerce is popularized, crimes related to Electronic Commerce are also increasing, Electronic shopping malls and payment gateways focus their attention on network security of payment information or the sizes of encryption keys, In real world, however, the payment-related crimes in electronic shopping malls are not based on the security hole of encryption mechanism of the payment systems, but on the customers carelessness or the insecurity of server systems of merchants or financial institutes. So, this research analyzes the structure of current electronic payment systems, investigates the payment-related crimes, addresses the structural problems of the Korean electronic payment systems, and suggests an alternative general architecture for secure payment systems by incorporating the concept of separation of order information and payment information.

Advances in information and telecommunications technology are producing unprecedented shifts in the way businesses conduct their business, Today, electronic commerce is becoming pervasive due to, in large part, the widespread use of Internet and Worldwide Web. One element that plays an important role in shaping the success of electronic commerce is the electronic payment system. Deficiency in its reliability and security may lead to unwanted outcomes, including economic losses and customer dissatisfaction. By far, numerous forms of electronic payment systems have been introduced in the virtual marketplace. However, there exists little research that has focused on the characteristics of the electronic payment systems such that they may be compared with one another. This article is aimed at providing a framework for comparative analysis of electronic payment systems, examining the characteristics of the individual payment systems, and suggesting a choice strategy which enables a firm to select an appropriate payment system suited to their business needs. The framework classifies electronic payment systems into four categories including electronic cash, electronic checks, credit cards, and smart cards, and it can be employed in planning for an electronic commerce system.

In this paper, we propose about NFC-based mobile Easy Payment System. Already announced about kind of similar payment system by use smart phone NFC function. However this proposition system will uses an encrypted token and user indirect authentication. This feature makes through to simplify payment without other input necessary information. Also my proposition system has easy security certification process. This mean my system does not adequately to use payment of a large amount. But in retail payment will be very useful payment system.

Recent increase of commercial network Integration to World Wide Web(WWW) shifts an ordinary commerce to electronic environment. This draws more people to examine re-assurance of their secure transaction. This study investigates current status of security methodology for Electronic Payment System and extracts important axis of security level for electronic payment. Using these axis as security evaluation criteria, the research proposes a security matrix which consists of four different level of security granularity, hence allowing evaluation of a nation-wide credit card based payment system. Feasible usage of this matrix contributes to security analysis of the electronic system as whole, hence providing better secured electronic environment.

This paper analyzes the main factors affecting user selection of a small-sum electronic payment system using survey data of 396 users. Several findings emerge. First, users consider three pillars and eight factors in adopting a new system : system features(stability, security, and flexibility), transaction cost(payment commission and settlement period), and financial capability of provider(stability of financial structure, risk management capability, and funding capability). Second, the stability of the financial structure of the system provider is the most important factor to user acceptance of a new e-payment system. Users tend to consider uncertainty risk more seriously than transaction cost. This reflects the reality that electronic payment system service industry has not fully fledged yet. Third, some moderating effects exist according to payment methods and business usages. As for payment methods, speedy settlement cycle for wired/wireless phone payment, system stability for credit card and account transfer payment, and security for advance payment means are crucial factors. As for business usages, the stability of financial structure for online game content, system stability for music and video content, proxy payment commission for e-learning content, flexibility of the payment system for digital adult content, and security for public services are decisive ones.

The most important technical problem in EC is about secure electronic payment systems. Electronic payment systems come three different types distinguished by the payment method: electronic cash, electronic check, and creditcard. In these types, electronic cash payment system is popular and practical as in real commerce. But electronic cash can be copied easily, then it is infeasible to prevent user from double-spending a coin. In this paper, we overview several requirements for secure electronic payment system and present other proposed additions to the results. At last we present a model system which considers requirements above examined.
