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.

In recent decades, China's economy has grown rapidly and two-dimensional bar code-based payments services have been activated. This is a model that will be introduced by developing countries that lack mobile payment infrastructure, and countries that are looking to leap into cashless societies are also drawing attention. Along with this, the existing CRM market is expanding around the mobile device called m-CRM, and research is active on the importance of collective use for online advertising and two-dimensional bar code-based payments services. Therefore, through this study, we have explored the concepts and status of online advertising and customer relationship management which using the two-dimensional bar code-based system, and designed and implemented the method and mobile application system to effectively disseminate transactional advertising information at the point of sale or at the point of share. We also presented an application approach to look at the direction of two-dimensional bar code-based ads contents sharing system and its development.

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.

In these days, various wireless internet services are possible since the advanced wireless networks enable to transfer more data than before and smarter devices have developed to display the multimedia information more efficiently. Therefore, Korean MIPS such as SKT and LGT provide many kinds of advanced services such as wireless on-line shopping, mobile banking system and etc using 2.5 generation wireless network technology and smartcards. In a transportation system, a cellular phone can be used as a useful payment tool since most people always keep it and a mobile payment system has developed as infrastructure for wireless on-line services. In this paper, a mobile transportation payment system is introduced. A driver needs to pay a toll fee when he/she uses the highways. Recently, a high pass system has introduced, in which a vehicle can pass a toll gate without stopping to pay the fee to a counter. The payment is done automatically by an attached payment device. We have developed an advanced mobile system in which a smartcard embedded cellular phone is used as a payment device. The personnel and financial information is stored at a smartcard and the communication between the phone and OBU(On Board Unit) is done by Bluetooth.

In the recent IT field, the biggest concerns may be Mobile environment. This means that it becomes part of our life: the Mobile is applied to the areas of teaching, studying, commercial transaction, entertainment etc. In this paper, we implemented Mobile E-BOOK bookstore using WEB, DB, and a Mobile technology. This system takes duplex from to be available in Mobile WEB environment by PDA and actuality WEB site under desk top environment. This paper have presented big possibility in terms of embodied electronic commerce based on the Mobile-based E-BOOKstore system that has not attempted yet commercially.

비콘 서비스란 가까운 범위 안에 있는 사용자 위치를 찾아 메시지 전송, 모바일 결제 등을 가능하게 하는 스마트폰 근거리통신 서비스로, O2O 실현에 핵심적인 역할을 담당한다. 비콘을 활용하면 사물과 상황인식, 콘텐츠 푸시, 실내위치 측위, 자동체크인, 지오펜스 등 다양한 서비스 제공이 가능하다. 본 연구에서는 비콘을 활용하여 출석을 체크하는 자동 출석 시스템을 구현하였다. 자동 출석 시스템에서는 사용자가 강의실에 들어오는 것을 인식하여 출석 검사를 하며, 이 자료를 인터넷을 통하여 데이터베이스에 저장한다. 다양한 강의를 구별할 수 있으며, 들어온 시간, 나간 시간 등의 검사가 가능하며, 이를 좀 더 보완한다면 상황인식 시스템으로써 다양한 서비스와 연계시킬 수 있다.

Recently, More and more consumer enjoy the finance service such as settling, account transferring, stocks investment, and so via mobile device. In the mobile environment, data transferring between the devices is formatted as XML. However, the common XML file is exposed to the attack such as hacking and malignity code, to satisfy security of mobile environment is very difficult. The problem is more seriously at the open platform such as WIPI that is developed by our country. So there is enough reason to propose one system to protect the import data. In this paper, we development the system to digital signature and signature the XML document in order to protect data, and the system is observing the recommendation of the XML Signature Syntax and Processing by W3C. When designing and composition the system, we use the digital signature algorithm RSA, DSA, KCDSA, and HMAC, etc. we test the system at the open WIPI platform.

The Indonesian e-commerce market has grown significantly due to sustained economic growth, middle class growth, rapid increase in Internet and SNS users, and increase in accessibility of mobile broadband services. In particular, consumers' online shopping through mobile and SNS has been increasing rapidly based on the expansion of the popularity of smart phone devices. This research suggested the strategies for expanding exports of Indonesia through e-commerce platform to the Korean firms, with deep analysis of the current status and features, problems, cases, and implications etc. of Indonesia's e-commerce market. As an export expansion strategy utilizing Indonesia's e-commerce platform, this study showed the Korean firms have to build a local online distribution network, establish a logistics & delivery and payment system, acquire Halal certification for Muslim market, carry out the in-depth market research, actively implement Hanryu marketing strategy, develop a creative product, set up market segmentation strategies, and develop SNS mobile marketing.

가상화폐는 법정통화가 금융위기나 통화정책 등에 심각하게 영향을 받아 발생하는 문제점으로 시작하여 국가나 신용기관에 독립적인 전자지급결제시스템을 갖추는 것을 목표로 등장하게 되었다. 대표적인 가상화폐인 비트코인은 국제적인 유통수단으로 활용되고 있으며, 일부 국가에서는 납세 및 기타 법률과 같은 규제를 통해 관리되고 있을 정도로 영향력이 있는 가상화폐이다. 본 연구에서는 비트코인의 개념 및 현 상황에 대해서 분석한 후, 모바일 환경에서 채굴되는 M-Bitcoin을 제안하였다. 그리고 M-Bitcoin이 암호통화로써의 가치를 가질 수 있도록 신뢰성 확보를 위한 기술을 적용하고, 차후 현실에서 서비스되는 과정에 대해 연구하였다.

NFC(Near Field Communication) 기술은 스마트 폰과 같은 모바일 기기에 적용되어 정보의 송수신을 위한 매체로 활용될 뿐만 아니라 결제, 개인인증 등 다양한 분야에서 활용되고 있다. 따라서 이러한 NFC 기술을 이용해 개인정보를 활용한 다양한 맞춤형 서비스들이 등장하고 있으며 이에 따른 개인 정보위협의 부작용도 발생되고 있는 실정이다. 그러나 현재 NFC 서비스에서 발생할 보안 위협 요소에 대한 분석과 해결책에 대한 연구는 매우 미비하다. 본 논문에서는 NFC 서비스에 대한 보안 취약점과 NFC 기반 시스템에서 발생할 수 있는 공격들에 대해 분석하고, 이를 해결하기 위해 NFC 기반 시스템의 인증 메커니즘을 제안한다.
