Smart card is a useful tool used in electronic payment systems and it is very important to test whether a smart card operates correctly. In this paper, we analyze previous researches on testing smart cards, such as ISO/IEC and KS standard documents, and Guideline of Card Quality Test. We also propose the functional test results done on the Highpassplus card of Korea Highway Corporation. By testing the Hipgpassplus card we can get card systems with reliable functionality and security. Furthermore, this can help developing more reliable security systems. The test results of the Highpassplus card proposed in this paper are the first research on testing smart cards in services in Korea and we expect that the test methods of smart card will be advanced based on our results.

Recently introduced by the major credit card associations as replacements for the decommissioned SET and 3DSET protocols, the new payment models, 3DSecure and UCAF/SPA, have been designed to provide online merchants with a solution to an existing problem in online credit card transactions - the lack of an effective and efficient means of authenticating cardholders. The expected benefits arising from this added level of security from the merchant′s perspective are increased consumer confidence, significant reduction in the levels of fraud and charge backs and "liability shift". Using data gleaned from preliminary interviews, discussion forums and promotional material, we present a critical analysis of the potential barriers and facilitators that will impact on the widespread traction of these programs in the marketplace in the coming years.

This paper proposes a Near Field Communication (NFC) communication system that exchanges information of digital business cards efficiently for many to many communication to solve inconvenience of one-to-one communication when people exchanges business cards each other in meetings such as conference, forum, seminar. The proposed system can provide people to exchange contact information one-to-one as well as multiple members at once using a digital business card system that consists a server and a database based on NFC communication. The system has been developed to collect business card information from a NFC reader and to transfer it directly to a smartphone application effectively. The system can manage business card information with the application effectively and provide security in order to prevent from leakage of private information when transferring contact data.

A smart business card printing system that automatically prints business cards requested by customers online is being activated. What matters is that the business card submitted by the customer to the system may be abnormal. This paper deals with the problem of determining whether the image of a business card has been abnormally rotated by adopting artificial intelligence technology. It is assumed that the business card rotates 0 degrees, 90 degrees, 180 degrees, and 270 degrees. Experiments were conducted by applying existing VGG, ResNet, and DenseNet artificial neural networks without designing special artificial neural networks, and they were able to distinguish image rotation with an accuracy of about 97%. DenseNet161 showed 97.9% accuracy and ResNet34 also showed 97.2% precision. This illustrates that if the problem is simple, it can produce sufficiently good results even if the neural network is not a complex one.

At the time the local credit-card companies plunged into a liquidity crisis in 2002, S-Card was urged to take into account the estimated customer income (ECI) to enhance its customer credit evaluation function for the first time in Korean financial industry. Before this new attempt by S-Card, most credit-card companies including S-Card had performed a customer's credit evaluation based on the customer's behavioral factors such as the amount of purchase on credit, debt payment, and financial history that is provided from the Credit Bureau. However, this approach failed to measure customer's potential value which is one of the major factors in judging the customer's ability to pay, and hence, led to difficulties in risk management. The purpose of this case study is to present the better approach to sophisticated risk management for financial firms in Korea by reviewing S-Card's process of customer income estimation and its application to risk management.

The current research examines whether consumers' preference for credit card benefits (i.e., general credit card benefits vs. credit card benefits related to green life) differs according to their pro-environmental disposition. Specifically, we predict that for consumers with high (vs. low) pro-environmental disposition, their preference for credit card benefits related to green life will be higher, while preference for general credit card benefits will not be different between low and high pro-environmental disposition groups. An online survey (N = 487) was conducted to test the hypotheses. Consistent with the hypotheses, the results indicate that (1) respondents with high pro-environmental donation intention, as compared to those with low pro-environmental donation intention, had higher preference for credit card benefits related to green life; and (2) there was no significant difference in preference for general credit card benefits between high and low pro-environmental donation intention groups. We suggest an important insight into how credit card companies approaching ESG issues can increase their consumers' preference for credit card benefits relevant to green life, considering consumers' individual differences such as pro-environmental disposition.
