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.

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.

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.

The purpose of this study was to identify the characteristics of late credit card bill payers. Data were collected through a questionnaire survey of 621 credit card users residing in five metropolitan cities including Seoul and Gyeonggi Province. The results indicated that credit card delinquents showed irrational behavior in managing the use of credit cards. That is, they unnecessarily subscribed for credit cards, used their credit cards without signature, or excessively used the credit cards regardless of their payment capability. From these study results, two recommendations were made : 1) consumer education on credit card use and credit management and 2) law revision on regulating credit card use.

Recently, personal business styles have been rapidly changed into e-business due to the rapid progress and deployment of Internet. As a result of the change, new and safe ways of payment such as electronic wallet, electronic money and electronic check have been developed and introduced. In this paper a secure and user-friendly payment method is addressed. One of most important reasons why newly developed safe payment methods are not widely used in e-business is lack of convenience for the users. On the other hand credit card based payment, which is traditional one, is the most prevailing due to the user-friendliness. However this payment also has some problem in sense of security. In this paper, we design and implement a secure credit card-based payment system using one-time credit information. The main features are "payment information must be new", "can use the old credit system", and "do not require client software".

스마트폰 사용의 증가로 인해 모바일을 통한 결제가 대중화되고 모바일카드 이용자도 급격하게 증가하고 있다. 현재 사용되어지는 모바일카드의 대부분은 USIM(Universal Subscriber Identification Module) 칩에 신용카드 정보를 다운받아 사용자에게 서비스를 제공한다. USIM에 저장되는 모바일카드는 통신사의 USIM 칩에 보안을 위한 최소한의 정보를 저장하고 관리하며 PKI(Public Key Infrastructure) 기반의 인증서 체계를 사용하고 있다. 그러나 PKI 기반의 결제 시스템의 경우 처리 절차가 복잡하고, 인증서 및 CRL(Certificate Revocation List) 관리에 많은 비용이 필요하다. 특히 인증서가 없는 외국인의 경우 국내 전자상거래를 이용할 수 없기 때문에 국내 전자상거래 발전을 저해하는 요인으로 작용할 수 있다. 따라서 본 논문에서는 인증서 사용의 문제를 해결한 모바일 환경에 적합한 무인증서(certificateless) 기반의 서명 암호화 기법을 이용한 안전한 신용카드 결제 프로토콜을 제안한다.

The research aims to help merchant acquiring institutions gain a better insight on what merchant establishments in the Singapore market perceive of the costs they incur due to credit card acceptance. The research attempts to study the Singapore market and establish if increased credit card usage does increase costs for the merchant establishments that accept credit cards, this will help to acquire institutions in Singapore have a better understanding of merchant perceptions and what drives or deters credit card acceptance in the Singapore market. The survey was based on an interview of merchant establishments and the views of the merchants and was not based on their financial data. As a first step, the variables used in the survey were tested for interdependence using Chi-square tests; subsequently data reduction using factor analysis was performed and finally linear regression to establish a relation between dependent and independent variables. Merchant establishment believe accepting credit cards and increasing volume is costlier compared to another form of payment, but have mixed awareness about interchange fee. It also indicated that interchange fee and cardholder benefits are independent of the merchant establishments. The study only broadly attempts to gauge merchants view if increased credit card usage has increased costs for them.
