최근들어 스마트폰을 활용한 이용분야가 급속도로 다양해지면서 이를 이용한 모바일 금융결재 시스템이 다양하게 등장하고 있다. 하지만 이러한 등장에도 불구하고 모바일 결재시스템 사용은 널리 이용되지 못하고 있는 실정이다. 따라서 본 연구에서는 모바일 결재 시스템을 대상으로 사용품질 요인이 사용자의 신뢰와 사용지속의도에 미치는 영향을 살펴보고자 한다. 본 연구결과를 통해 모바일 결재시스템의 시스템 구축에 대한 전략적 가이드 라인을 제시할 수 있는 기반이 될 것이다.

모바일 결제시스템의 다양한 특성에 힘입어 많은 사용자는 언제 어디서나 시간과 장소의 제약에서 벗어나 다양한 제품을 손쉽게 구매할 수 있게 되었다. 이러한 측면에서 본 연구는 모바일 결제시스템 사용자들의 특성(인구통계적 특성, 모바일 결제시스템 이용특성)에 따라 모바일 결제시스템이 갖추어야 하는 특성(보안성, 호환성, 효율성, 경제성, 신뢰성)에 대한 인식도가 어떻게 달라지는가를 실증적으로 규명하고자 하였다. 한국과 중국의 모바일 결제시스템 사용자들을 대상으로 설문지를 활용한 실증분석을 실시한 결과, 사용자들의 성별과 국적에 따라 모바일 결제시스템의 일부 특성에 대한 인식도에 있어서 차이가 존재하고 있음을 확인하였다.

최근 결제 시스템은 인간 친화적이며 다양한 디지털 기술들의 발전으로 간편화되고 있다. 특히 핀테크의 일종인 간편 결제 시스템은 효율성과 간편성을 강조하면서 금융 시장에서 크게 화두 되는 시스템이다. 그러나 효율성과 간편성에 집중하다 보니 보안성이 낮아지는 단점을 가지고 있다. 특히, 간편 결제 시스템의 핵심인 토큰 시스템의 취약점은 가장 큰 문제를 발생할 수 있다. 이에 대응하기 위해, 이 논문에서는 기존 결제 시스템 방식에 비대칭 암호화 방식을 추가하여 간편 결제 시스템의 보안성을 높여 토큰 취약점 대응 시스템을 제안한다.

Due to the development of mobile technologies, the carrier (telecommunications) billing service market is rapidly growing. carrier (telecommunications) billing service allows users to make on-line purchases through mobile-billing. Users find this particularly convenient because the payment acts as a credit transaction. Furthermore, the system is commonly believed to be secure through its use of SMS (Short Message Service) authentication and a real-time transaction history to confirm the transaction. Unfortunately, there is a growing number of fraudulent transactions threaten the future of this system. The more well documented types of security breaches involves hackers intercepting the authentication process. By contaminating the device with security breaching applications, hackers can secretly make transactions without notifying users until the end of month phone bill. This study sheds light on the importance of this societal threat and suggests solutions. In particular, "secure" systems need to be more proactive in addressing the methods hackers use to make fraudulent transactions. Our research partially covers specific methods to prevent fraudulent transactions on carrier billing service providers' systems. We discuss about the proposed improvements such as complement of electronic payment systems, active promotion for fraudulent transactions enhanced monitoring, fraud detection and introduce a new authentication service. This research supports a future of secure communications billing services, which is essential to expanding new markets.

As smart phones have became popular in recent years, use rate of smart phones application of mobile subscribers is now gradually increasing. Smart phones have a considerable effect on real life of users. Especially, mobile payment service using smart phones is outstanding in convenience because of its simple way to check out online. Therefore, in this paper, the database was designed for inquiring and making pre-order for take-out products based on connivence. This paper offers pre-order design to have order information standardized, menus which store owners can register and manage, and statistical data based on sales. It can be cost and time-efficient by using integrated pre-order system across all franchises. If this take-out pre-order system becomes more widely available, it will increase profit for both users and franchises due to cost and time efficiency.

NFC is enable communication between wireless davice within a distance of 10cm, one type of non-contanct short-range wireless communicaton using 13.56MHz frequency band. This is one type of RFID technology which include file transfer, contactless payment and RFID. NFC technology is standardized in 2003 already, it received much attention recently because NFC is announced full support in Android 2.3. And as APPLE is announced that have plan to monunt in iphone 5,mobile payment system is expected to change. Already SAMSUNG is launched NEXUS S mounted NFC chip and announced NFC chip will be mount GALAXY S2 LG Electronics is statemented NFC chip will be mount on smart phone that will realese this year. In this study, will announce about analysis for NFC technology and recently trend and used case.

The 2018 Seoul Zero Pay is a policy actively promoted by the government as an economic stimulus package for small business owners and the self-employed who are experiencing economic depression due to COVID-19. However, the controversy over the effectiveness of Zero Pay continues even after two years have passed since the implementation of the policy. Zero Pay is a joint QR code mobile payment service introduced by the government, Seoul city, financial companies, and private simple payment providers to reduce the burden of card merchant fees for small business owners and self-employed people who are experiencing economic difficulties due to the economic downturn., it was attempted in the direction of economic revitalization for the return of alleyways[1]. Therefore, this study intends to draw implications for improvement measures so that the ongoing zero-pay can be further activated and the economy can be settled normally. The analysis results of this study are as follows. First, it shows the effect of increasing the income of small business owners by inducing consumption in alleyways through the economic revitalization policy of Zero Pay. Second, the issuance and distribution of Zero Pay helps to revitalize the local economy and contribute to the establishment of a virtuous cycle system. Third, stable operation is being realized by the introduction of blockchain technology to the Zero Pay platform. In terms of academic significance, the direction of Zero Pay's policies and systems was able to identify changes in the use of Zero Pay through big data analysis. The implementation of the zero-pay policy is in its infancy, and there are limitations in factors for examining the consumer image perception of zero-pay as there are insufficient prior studies. Therefore, continuous follow-up research on Zero Pay should be conducted.

As the population of camping is increased in campsites and auto camp sites, the electrical equipment can safely supply electricity to users in a variety of electricity bill policy is required in the campsite. In this paper, we develop the vending machine for electricity that can control the outdoor electrical outlet from the management server using the Z-Wave WPAN and android mobile application. The developed vending machine for electricity consists of the management server, the controller, the outdoor outlet box, and the mobile application. The management server provides reservation and electricity bill payment to users. The management server controls the electrical outlet box through the controller to safely supply electricity to users. The controller that is a relay device between the management server and the switch controls switches based on Z-Wave mesh network. Outdoor electrical outlet box has 2 meter switches. We receive the relevant authorization to provide commercial electricity services using the outdoor electrical outlet box in the campsite.
