Recently, applications range of NFC is widening by popularization of smartphone. Expansion of NFC means generalization of electronic payments systems. So security of NFC is very important. AES-128 is safe cryptographic technique for NFC now in use. But, the more range of applications increases, the more safe cryptographic techniques are necessary. In this paper, we propose the safe method is unaffected by the development of NFC. Proposed A-NFC scheme, adding the authentication of asymmetric cryptographic, is easy to apply for NFC and NFC-USIM chipsets, and it can adapt to the general NFC environment.

The NFC technology is contactless communication technology that one of the RFID/USN technology. NFC is available dual function that read and write without specified reader, and it is received attention because of high security and low price. This paper proposes design of a school guide system using NFC tag. First School visitants such as delivery man or the other person are confused about the location of building, so this system will be helpful in this situation.

As smart devices and OS with communication capabilities based latest NFC (Near Field Communication) have been spreaded, many applications with using existing RFID are being replaced to NFC. Smart NFC technology and existing services and devices can be easily combined convergence and advantage of smart phones, such as authentication and billing, medical care, the creation of a new paradigm of Network Communication are to be expected. By developing H/W, S/W of the Smart NFC Security Authenticator(SNSA), satisfying with wireless communication test results within accepted reference value, analyzing and testing the impact of topology, the signal performance of Daisy Chain Topology was much better than Star Topology's.

NFC (Near Field Communication) was developed by SONY, NXP in 2002 and in 2003 respectively. It is one type of standard shore-range wireless communication system which operates in 13.56 MHz frequency band, within 10 cm distance and enables data transfer between devices with maximum rate of 424kbps. Various studies have been done on NFC technology and many handset manufacturers such as Apple, Google, Samsung Electronics Co., are trying to expand their market for new mobile services using this technology. This paper analyses the NFC standard technology, its trends and prospects in chapter II, which is followed by NFC systems and communication method in chapter III, and eventually NFC trends and future views is explained in chapter IV.

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.

IT산업이 발전함에 따라 Bluetooth, ZigBee, RFID(Radio Frequency Identification)와 같은 근거리 무선통신 시스템에 대한 연구가 활발히 진행되고 있으며 다양한 분야에 활용되고 있다. 그 중 NFC(Near Field Communication)의 연구가 활발히 진행되고 있으며, NFC 태그와 함께 사용할 경우 활용성은 더욱 증대된다. 이와 관련하여 현재 다양한 NFC 태그관련 애플리케이션이 존재한다. 하지만 기존의 NFC 태그 애플리케이션은 단일 기능을 중심으로 제공하고, 여러 가지 기능을 이용하기 위해서는 여러 개의 NFC 태그가 필요하다는 단점이 있다. 이 점을 개선하고자 본 논문에서는 단일 NFC 태그로 다양한 기능을 제공하는 애플리케이션을 구현한다. 기능들로는 Text입력과 에어플레인 모드, Wi-Fi, Bluetooth, 무음모드, 알람, 알람설정, 사용자 지정 애플리케이션 선택 및 활성이 있다. 이러한 기능들은 사용자의 상황에 맞게 태그에 입력 시킬 수 있으며, 결과적으로 기존의 단일 기능을 제공하는 애플리케이션보다 개선됨 점을 나타낸다.

Recently, interest is rapidly increasing in short-range wireless communication such as NFC (Near Field Communication). In order to minimize the attendance time, we propose the attendance management system using the NFC tags attached in all of the desks in a classroom and NFC readers embedded in most of the smart-phones released in lately. The system consists of PC version web-application for professors and the android version app-application for students. And it provides the professors with more lecture time by saving the attendance check time. The contribution of this paper include that it proposes and develops the prototype of the attendance management system using NFC and proves that the system is applicable to the various kinds of educational organizations.
