최근 자판기 분야에 있어 카드, 모바일 등을 이용한 전자화폐 결제시스템은 하나의 대세적 흐름을 형성하고 있다. 무엇보다 편리한 결제수단이라는 점과 매출증대 효과 등을 고려할 때 전자화폐자판기는 앞으로 확산속도가 무척 빨라질 것이다. 전자화폐자판기 시대를 향해 발 빠른 행보를 내딛고 있는 상황에서 과연 전자화폐가 자판기를 통해 어떻게 결제가 이루어지고 어떠한 운영효율을 거둘 수 있는지 세부적으로 살펴보는 것도 의미 있는 일일게다. 새롭게 기획된 뉴 테크놀로지에서는 웹케시사의 Magic@NET 자판기 시스템에 대해 자세히 살펴 보았다.

최근 디지털 금융 기술의 발전에 따라 모바일 간편 결제가 보편화 되고 있다. 이러한 시대에 발맞추어 외식업체, 또는 대형 식품 프랜차이즈 기업들은 자체 모바일 결제 시스템을 도입하는 추세이다. 하지만 소규모 자영업자들은 기존 시스템과의 호환 및 비용 문제 등으로 새로운 시스템을 도입하기가 어려운 실정이다. 스마트 POS(Point of sales)를 표방하여 소규모 사업자를 대상으로 시장에 나온 몇 가지 제품이 있지만, 이 제품들은 별도의 애플리케이션을 매장과 고객의 모바일 기기에 설치해야 하므로 접근성이 떨어지는 단점이 있다. 이에 본 논문에서는 별도의 설치를 하지 않아도 이용이 가능한 Web 기반의 POS 시스템을 제안한다. 이 시스템으로 매장은 효율적인 매출 및 관리뿐만 아니라 고객과의 Interaction 또한 증가시킬 수 있다.

The increase of the smartphone users has popularized the mobile payment and the mobile credit card users are rapidly getting increased. The mobile credit cards that currently used provide its users with the service through downloading mobile credit card information into USIM. The mobile credit card saved in USIM has the minimized information for the security and is based on PKI. However certificate-based payment system has a complicated procedure and costs a lot of money to manage the certificates and CRL(Certificate Revocation List). Furthermore, It can be a obstacle to develop local e-commerce in Korea because it is hard for foreigners to use them. We propose the secure and efficient mobile credit card payment protocol based on certificateless signcryption which solve the problem of certificate use.

With the rapid increase in mobile device users, there are many cyber attacks using SMS messages to infect the mobile device. The monetary demage from those attacks are also increasing. Since those demage are generally related to mobile micropayement systems, we study the details of the incidents on smishing and mobile micropayment. We have identified several limitations of current regulations and laws of them. Thus, we propose new regulations and laws to reduce the financial demage from simishing and to strengthen the security and responsibility of the mobile network operator, payment gateway, and content providers who are participating in the structure of a mobile micropayment systems, such as a regulation for information security evaluation system, several laws for compensation of financial demage within mobile micropayement system.

In the process leading to the continuous use of mobile payment system users, emotional and cognitive reactions are carried out. In this study, a questionnaire was conducted to determine the effect of external factors(social, system, service factors) of the mobile payment system on the continuous use of emotional responses(pleasure, emotional trust) and cognitive responses(cognitive trust). The structural model was tested using SPSS and PLS. As a result of the analysis, it was found that external factors affect emotional and cognitive responses, and cognitive responses affect continuous use.

This study aimed to compare the systems of ticketing application programs of three major movie theaters, CGV, Megabox, Lotte Cinema, with each other and evaluate the usability, and find problems to figure out user experiences for more convenient mobile ticketing. Experimental subjects with experiences of using apps of the movie theaters were recruited; First, as a primary task, they reserved movie tickets with each of the movie theater apps; Second, they had in-depth interviews with questions based on the model of Creating Pleasurable Interfaces by Stephen Anderson. As a result, users preferred the composition with information in order in overall, in which ticketing process went smoothly. In particular, users were more satisfied with convenient payment applications. Therefore, as an improving way, it is required to design an interface for users to recognize at a glance and a payment system within an app, not to design separate payment system out of the app. I hope this study will help actively conduct researches to maximize the usability in a way to reserve movie tickets through smartphone apps.

Recently, most of the modern people used a second mobile device(two degree mobile device). Mobile devices are affecting all areas of human life, consumer electronics, transportation, manufacturing, and finance. On this paper, we propose a model-driven development based interaction model that can be used in the development of mobile payment system, which is the latest buzzword pins of the various application fields of mobile devices Tech (Fin-Tech) sector. Using a model-driven development based models do not depend on the Platforms (PIM), we propose a model for interaction between devices which can be reused when developing mobile billing app. A model-driven development based mobile applications use the reusable of interaction models development program analyzed the bus fees automatic payment application by a beacon.

Local area festivals have grown on a scale for the past 20 years, but have suffered ups and downs. Through the trial and error of the festival operation, problems such as prediction of the number of visitors, planning of event scale, calculation and expansion of sales volume, and management of various participants in the duration were highlighted. To solve, this study designed and developed a mobile payment system and festival operation management system for local scale festivals as a platform operating system of web and app combined. The results of this study presents four basic functions. It includes ticketing management, attendance identification and entrance control, charge of festival currency and use of payments, real-time provision and management of related information, and performance reporting for each role. It was applied to local festivals in practice as to enable local shop owners to participate in advertisements or sponsorships and confirmed their contribution to local commercial market and the revitalization of festivals through this system.

본 논문에서는 이동성이 많은 결재자의 업무를 효율적이고 신속하게 처리하기 위해 PDA, 핸드폰과 같은 모바일 장비상에서의 공인인증서를 이용한 결제처리 및 무선 인터넷상의 보안기능을 갖춘 시스템을 개발하였다. 모바일 인터넷의 보안 메커니즘은 정당한 사용자인지를 확인하는 인증, 데이터의 비밀 전송과 변조 여부 확인, 전자서명을 통한 거래 부인 방지 등이 이뤄진다. 이를 위해 RSA 공개키 알고리즘을 사용하여 문서 내용들에 대한 암호화/복호화를 수행하며 SHA-1 해시 알고리즘과 공인 인증서를 사용하여 결제처리를 한다. 일반 데스크 탑뿐만 아니라 모바일 장비간의 데이터 패킷 전송을 위해 XML 인코딩과 SOAP 프로토콜을 이용한다.
