In this paper, we propose about NFC-based mobile Easy Payment System. Already announced about kind of similar payment system by use smart phone NFC function. However this proposition system will uses an encrypted token and user indirect authentication. This feature makes through to simplify payment without other input necessary information. Also my proposition system has easy security certification process. This mean my system does not adequately to use payment of a large amount. But in retail payment will be very useful payment system.

Near Field Communication has been emerged as a spectacular phenomenon. The aim of this study is to determine the factors influencing the adoption of NFC-enabled mobile payment. In order to analyze, this study proposes a research framework based on Technology Acceptance Model. 353 valid data were collected through the Internet who has used NFC technology. Results show that relative advantage, social influence, and technology availability have a significant effect on perceived usefulness ($0.190{\ast}{\ast}{\ast}$, $0.211{\ast}{\ast}{\ast}$, $0.227{\ast}{\ast}{\ast}$respectively). However, for perceived ease of use, only relative advantage and social influence were verified to have significant influence. Perceived ease of use significantly influence perceived usefulness ($0.348{\ast}{\ast}{\ast}$), and both of them significantly affect the NFC-payment adoption intention ($0.199{\ast}{\ast}$, $0.361{\ast}{\ast}{\ast}$). The results also verified the moderator variable of personal innovativeness ($0.20{\ast}{\ast}{\ast}$ and $0.297{\ast}{\ast}{\ast}$respectively).

We categorize the model of simple payment into Magnetic Secure Transmission, Near Filed Communication, and App Card based on the Focus Group Interview. We also define the key drivers for the diffusion of simple payment services based on the literature review with the experts. Through Analytic Hierarchy Process our finding suggests that the degree of acceptance at the stores is the most critical factor which decides the diffusion of simple payment service model. Security is also the important driver but due to the fact that service providers should follow the information security rule and supervisory guidance, it actually did not make a big difference in terms of assessing competence of each model.

NFC란 Near Field Communication의 약자로, 양방향 통신을 지원하는 근거리 통신 방법으로, 저전력, 사용의 편이성 등이 새롭게 각광받고 있는 차세대 통신수단이다. 본 논문에서는 기존의 바코드와 유사한 QR코드와 NFC를 모두 이용하는 모바일 환경에서의 소셜 커머스 결제 시스템을 제안한다. NFC를 사용하여 결제하는 제안된 방식이 기존의 결제 방식에 비하여 간편하고 편의성이 증대됨을 보인다.

최근 스마트폰에 탑재된 NFC를 통한 결제 서비스의 시장이 각광을 받고 있다. 사용자는 자신의 신용카드 정보와 같은 지불 수단을 스마트폰에 탑재된 NFC 장치에 기록하여 리더기에 그 정보를 보냄으로써 간편하게 결제를 할 수 있게 되었다. 하지만 무선 신호의 특성상 사용자의 정보가 외부로 노출될 가능성도 배제할 수 없으며, NFC 데이터를 읽는 리더기가 신뢰 가능한 리더기인지 알 수 없는 보안 취약성이 존재한다. 본 논문에서는 NFC를 통해 안전하게 데이터 통신을 할 수 있도록 정의된 NFC-SEC 표준에 대해서 살펴보고, NFC-SEC 프로토콜에서 피어 간의 상호 인증의 필요성에 대해서 말한다.

최근에는 많은 스마트폰 어플리케이션이 결제와 할인쿠폰, 적립 등 각종 기능을 제공하면서 사용자들에게 매우 간편한 거래 방식을 제공할 수 있는 NFC 서비스 시장이 성장할 것으로 전망되고 있다. 특히 스마트폰의 NFC 기능을 이용한 여러 서비스들 중 모바일 쿠폰 서비스인 mCoupon 서비스의 시장 활성화를 위해 다양한 인프라가 구축되고 있다. 하지만 mCoupon 서비스는 아직까지 관련 보안 연구가 미흡한 상태이며 보안 기술 개발 속도 또한 현재 구축되고 있는 다양한 인프라에 따라가지 못하고 있다. 따라서 본 논문에서는 NFC 환경에서의 mCoupon 서비스를 위한 안전하고 효율적인 쿠폰 시스템을 설계하고 구현한다.

Recently, as the number of Smart Phone users increase, the simple payment system has been able to make payments using only card information such as a registered password without extra authorized certificate authentication or input of card information. In this paper, it will examine and analyze simple payment system provided by IT companies and financial institutions and the simple payment system that operates global online payment system by case view of operational direction. Then with this examination, it will study ways to improve the problems with terms of convenience and stability in terms of users. In this paper, it will analyze the inconvenient problem in using the QR code system that recently introduced and will propose solutions. Also, it will propose suggestions to solve inconvenience that caused by system that supports NFC simple payment terminal in Korea is not universalize by analyze case study on the overseas simple payment system. It will also propose opinions on the matters that customer having responsible for event of a small financial accident related to loss or theft when using the simple payment system. Then it will suggest expected requirements to prepare new security technical countermeasures and solve the conditions of meeting expectation satisfaction of users.

Wireless communication technology such as NFC and RFID makes the data transfer between devices much easier. Instead of the irksome typing of passwords, users are able to simply authenticate themselves with their smart cards or smartphones. Relay attack, however, threatens the security of token-based, something-you-have authentication recently. It efficiently attacks the authentication system even if the system has secure channels, and moreover it is easy to deploy. Distance bounding or localization of two devices has been proposed to detect relay attacks. We describe the disadvantages and weakness of existing methods and propose a new way to detect relay attacks by recording a background noise.
