  • 스마트폰, 태블릿 PC 등 2010년부터 폭발적으로 보급 확산된 스마트 디바이스의 영향으로 모바일 결제 분야에 가장 핫이슈로 떠오른 기술이 바로 NFC (Near Field communication) 기술이다. 사실, NFC 기술은 2004년부터 표준이 개발되었지만 이를 적용할 디바이스 및 서비스의 부재로 활용이 되고 있지 않다가 2011년 구글이 구글 월렛 서비스를 시작하면서 본격적으로 NFC 기반 서비스가 적용되기 시작하였다. 국내에서도 2011년 11월 명동 NFC 존 시범 사업을 통해 모바일 결제, 스마트 포스터, 스마트 주문 등 다양한 NFC 기반 서비스를 추진하였다. 이렇듯 국내외에서 다양한 NFC 기반 서비스 발굴 및 활성화에 노력을 기울이고 있기는 하지만, 보안을 고려하지 않은 서비스 제공 시 이에 대한 사고 피해는 상상을 초월할 수 있다. 특히, NFC 기반 서비스의 대부분이 사용자의 금전적 결제를 요구하는 서비스라는 점이 이를 입증해준다. NFC 기술 자체에는 보안 기능이 일부 포함되어져 있기는 하지만 NFC 기반 서비스별 보안 취약점이 존재할 수 있다. 이에 따라, 본 논문에서는 NFC 기반 서비스별 보안 위협 취약점 분석 및 해당 위협 및 취약점에 대한 기술적 제도적 보안 대책 등을 제시한다.

  • Most recent trend reveals broader state of provision of NFC service as NFC technology was applied on smartphones which has become core communication tools by providing integrated services such as payment, medical, and personal authentication. Moreover, with integration of original service and NFC technology, new service providers now can handle personal information of original service or can handle other personal information with transition of previous service provider to NFC service provider. Considering current state of security industry along with NFC technology and service, we would like to analyze current stage of security threats and plan the counter strategies to create NFC service structure.

  • The rate of disappearance people such as children, demented elderly, and disabled is being increased every year. In this paper, we suggest accident prevention system for second class citizens which is based on Bluetooth and NFC to prevent second class citizens' disappearance. Nowadays, most of people are using a smart phone, and these smart phones usually have Bluetooth and NFC module. Therefore in this paper, we would design and implement the accident prevention system for second class citizens and their guardians by using smart phones which have Bluetooth and NFC module.

  • One of problems in car navigation systems is that a number of inputs are required for a directions search. This may even causes a car accident due to poor concentration while driving. In order to solve the issue we design and implement a safe and easy-to-use car navigation system which allows a driver to look up directions with just a single tap. Our smartphone app creates an NFC tag by deriving location information from a text, voice, GPS, and so on. The driver can then get the directions by just tapping a phone or card with the Tag on the navigation system. We show the feasibility and effectiveness of our system by comparing our implementation with the existing car navigation systems.

  • In mobile market which has been developed drastically, short distance mobile Near Field Communication is becoming the conversation topic. Google adopted this NFC technology to Android 플랫폼 for securing the leadership and many another countries including domestic companies are putting spurs to develop service and technology by connecting mobile carrier and the financial. Within this circumstance, most noticeable issue is securing stability of nfc application service. Android 플랫폼 is operating system of mobile device and also a software stack which is required limited hardware and immediate response. However, since its structural characteristic which is suitable for limited hardware, the response is not quite stable for real time process. That is, this paper researches by analyzing real time response of NFC related library provided from Android 플랫폼 and applying the result to NFC application for securing stable data process and response.

  • Near-Field Communication(NFC) is a useful technology that is receiving worldwide attention. NFC mobile payment systems are being developed by many technology companies including financial institutions especially for the public transportation. In this research we find several factors for the intention to adopt NFC payment system. We surveyed 355 respondents who live in Ho Chi Minh city, Vietnam which became more interested by Korean as a post China country to test our research hypothesis. Using Technology Acceptance Model(TAM) we find that the factors of Social influence, Trust, Security, and Users' Convenience play the significant role to the factor of Intention to Use of NFC payment system.

  • In this paper, we study the complex mobile antenna for WPT(Wireless Power Transfer) with NFC(Near Field Communication) of inductive coupling using FPCB which has half thickness compared with the existing coil type antennas. Considering the pattern thickness of loop antenna, the analysis of electromagnetic wave absorber and battery's influence, absorber thickness, the ranges of design parameters are obtained. The proposed antenna has 0.45 mm thickness using single layer 3 oz FPCB and absorber. From measurement, the characteristics of NFC antenna can be satisfied with the specifications of EMVCo. and domestic mobile telecommunication and the transmission efficiency of the proposed WPT antenna is 68.1 % which is competitive with the existing coil type antenna. From the results of this paper, it has been confirmed that the proposed antenna can be used as the WPT and NFC antenna for mobile phone.

  • This paper introduces the development of HF(NFC) and UHF band(13.56 MHz, 920 MHz) tag antennas, imbedded in a box. In dual band antennas, the HF band tag can be used to inspect the box using NFC, and the UHF band tag can be used for logistics. The dielectric constant of the box material is measured and used for simulation. The Ntag213 chip manufactured by NXP is used in HF loop antennas, since NFC is possible with Ntag213. For the UHF band, the Higgs-3 chip manufactured by Alien is used. The HF tag antenna is located at the center of the UHF tag antenna, and the location of the HF tag antenna is calculated while considering coupling effects. The designed tag can be used by both the bands for the purposes of logistics and authentication.
