Payment system is defined as the various contracts and operating facilities for the transfer of monetary value to clear the relationship between credit and debt. Payment systems essentially require the efficient and reliable operations. Card-based payment systems are developed practically and creatively in accordance with the progress of ICT. Especially in mobile environment with intelligent mobile devices such as smart-phones and tablets, a variety of payment services are provided. Existing card-based payment services are configured by the payment transaction initiated by the merchants card acceptance and then swiping into the CAT (Card Authorization Terminal) to begin the transaction. The merchant initiated payment services are now applied to the Wireless CAT (W-CAT) for mobile environment. That kind of payment services cause many problems such the illegal card information leaks and the lingering threat of W-CAT theft. Also, the use of many W-CATs increased cost to the merchant. In this paper, we propose the card holder initiated card payment system using the intelligent mobile devices in mobile environment for solving problems of the existing merchant initiated card payment system and coping effectively with the activation of a wireless data network and changes of information technology.

This paper introduces a new credit card payment scheme called No Number Credit Card that can significantly reduce the possibility of credit card fraud. The proposed payment system is loosely based on Kerberos, a cryptographic framework that has stood the test of time. In No Number Credit Card, instead of card numbers, only payment tokens are exchanged between the customers and merchants. The tokens are generated based on the payment amount, payment type, client information, and merchant information. However, it does not contain the credit card number, so the merchant or a database hacker cannot acquire and illegally use any credit card numbers. The No Number Credit Card system is ideal for online e-commerce transactions and can be used with any credit card that users possess. It can be used with minor modifications to the current card payment system. We provide the principles of its operation through scenario analysis, a sample implementation, and a security analysis

The purpose of this study is to estimate the rate of credit card payment for private education. The results of study can be used to improve credit card handling problems of private educational institutes, leading toward improvements in income transparency, increase in tax burden equity and long-term economic welfare improvement for individual households. 424 households out of 586 household that were surveyed in September of 2002 had 1,700 cases private extracurricular education. 67 of the 1,700 cases that did not have expenditure records were removed from the analysis. Only 3.67％ out of 1,633 cases were paid by a credit cards and the amount of credit card payment were only 5.65％ of the total amount spent for private education. The average fee of private educational institutes that allow credit card payment was higher than the fees of private institutes which don't allow a credit card payment or those of private institutes where consumers don't know whether a credit card payment was allowed. The average fee of private education paid by credit cards was 34,465.46 won higher than that paid by cash. Credit card payments to private educational institutions is an important social issue with respect to fair tax collection and tax burden equity since most private educational services operate in fairly small sizes and are offered by the self-employed, and the expense of private education is a fairly large proportion of the household income. It is also important for consumers if credit card acceptance expands alternatives that consumers can choose in private education. Therefore, credit card payment should be encouraged in private extracurricular education. To do this, private education providers should be forced to join a credit card payment service by the National Tax Service. A regulation that prohibits the refusal of credit card payments should be required, and credit card service charges of private education providers should be incrementally decreased. Also, consumer education and public promotions for credit card use instead of cash in paying for private education fees are recommended.

본 논문은 여러 개의 신용카드를 이용하여 한가지 상품을 구매하는 것을 가능하게 하는 '분할 가능한 신용카드 결제 시스템'을 제안한다. 이 카드 결제 시스템 구조의 가장 큰 장점은 기존의 카드 결제 시스템의 제반구조에서 두가지 방법으로 구조를 변형하였다. 첫째로 판매자에게 그들이 해당 카드 발급 기관으로부터 분할결제가 가능하도록 카드 승인 과정을 제어할 수 있는 V-Card Manager(VCM)가 추가된다. 두 번째로 소비자가 그들의 선호에 따라서 사용자에게 맞추어져 분할 결제가 가능한 카드를 생성할 수 있도록 소비자 자신들에게 V-Card Agent(VA)가 설치된다. 본 연구는 고객의 이익과 선호에 따라서 분할 결제를 가능하게 하는 맞춤형 신용카드 결제방법을 제시한다.

본 논문에서는 인터넷 쇼핑몰에서 신용카드 전자결제에 대해 다루고자 한다. 전자결제는 전자상거래 분야에서 매우 흥미 있는 주제 중에 하나이다. 전자결제 방식 중 신용카드 결제는 현재 인터넷 쇼핑몰 전자 결제의 대부분을 차지하고 있다. 최근 중국의 인터넷 쇼핑몰은 매우 빠른 속도로 성장하고 있으며, 동시에 전자결제에 대한 관심도 많이 높아지고 있다. 아직은 다른 나라와는 달리 중국에서 신용카드 결제가 활성화되지 못하였지만, 향후 신용카드의 사용은 매우 빠르게 증가할 것으로 기대되고 있다. 본 논문에서는 중국의 인터넷 쇼핑몰에서 신용카드 결제에 영향을 미치는 요인들에 대해 조사하고, 이 요인들과 신용카드 사용의도와의 관계를 분석하기 위한 모형을 제시한다. 그리고 제시한 모형을 검증하기 위해 중국의 인터넷 쇼핑몰 사용자를 대상으로 설문조사를 수행하고 구조방정식모형으로 분석한다.

최근 자기띠 방식의 금융카드를 IC 카드로 대체하기 위해 현금카드를 위한 금융IC카드표준 규격, 신용카드를 위한 EMV 규격을 채택되어 관련 인프라 구축이 활발하게 전개되고 있는 상황이다. 본 논문에서는 공개키 암호를 채택하고 있는 EMV 규격을 분석함으로써 인터넷 PKI, WAP PKI 등에 비해 상대적으로 연구가 미진한 EMV 기반 Payment PKI에 대한 연구를 하고자 한다. 이와 함께 IC 카드 기반 전자결제 시스템 개발에 활용할 수 있는 EMV 기반 Payment PKI 모델을 제안하고, EMV CA 시스템을 개발하였다. 또한 이를 활용하여 EMV 규격에 정의된 IC 카드 인증메커니즘을 보완하여 IC 카드 메모리 낭비 감소, 거래 처리 시간 단축, 효율적인 운영환경 및 성능을 향상시킬 수 있는 "효율적인 IC 카드 인증메커니즘" 제안하고, 성능평가를 하였다.

Purpose: The study is focused on understanding consumer behaviour related to credit card use in retail payment or identifying factors that influence risk perception. Research design, data and methodology: Based on data collecting from structured self-administered questionnaires of 247 Vietnamese bank account payers, this study uses the Cronbach alpha analysis, the factor analyses, the structural equation modeling to assess the research's measurement model and structural model with the presence of knowledge, propensity to trust, self-efficacy, risk perception, intended use and their complex, intertwined relationships. Results: The results reveal that customer's perceived risk, which is affected by their self-efficacy and propensity to trust, negatively impact on their intended use of credit cards in retail payment. However, there is no evidence of the significant influence of consumer knowledge on how they assess potential losses of credit card. Conclusions: These findings provide a better understanding of consumer risk perception, its antecedents and consequence in a direction of credit card adoption. Bank managers or marketers should focus on increasing the information about credit cards and issues related to credit card use in retail payment, promoting mechanisms to encourage customers to participate in the credit card experience.
