Currently using of card sway the our community together with developing industry, whether it is credit card or not any type of card, people have the card in the wallet. But these cards have a little problem like ragne of communication, data store term, and so on. So we adopt the bluetooth. Bluetooth has been watched on local wireless communication among the wireless communication method. Bluetooth has ranged from 10m to 100m for communication and dissipated low power. Besides bluetooth has the communication speed faster than communication method of other smart card. In this paper we designed the smart card which is automatically accounted without any payment.

In 2001, e-Credit guarantee system was introduced by the Korea Credit Guarantee Fund(KCGF) to extends the credit guarantee services for the purchasing amount on credit in the B2B e-Marketplace. It combines both the merits of bill of exchange and credit card and eliminates the uneasiness related to the unpaid accounts due to the non-facial e-Marketplace. The purpose of this paper is to empirically analyze both the causal relationship and influences among theoretical variables by the structural equation model(SEM). e-Credit guarantee system can be a good strategy for promoting B2R e-Marketplace. The level of application of e-Credit guarantee system is attributable to both the characteristics of B2B e-Marketplace and products. The cost reduction or saving in purchasing procedures, production and stockpiling will be possible through e-Credit guarantee system. The close linkage of financial institutions with the enterprises based on e-Credit guarantee system will further promote B2B e-Marketplace in Korea.

우리나라의 고령화 속도는 세계 최고의 수준으로 2018년 고령사회로의 진입이 예상되며 기대수명 또한 대폭 증가하여 100세시대가 도래하였다. 이에 따라 실버층의 욕구를 충족시켜 줄 제품이나 서비스에 대한 수요가 증가하고 있는데, 특히 베이비 부머의 실버층 편입으로 실버비즈니스에 대한 중요성과 관심이 더욱 부각되고 있다. 현 상황에서 대표적인 지급결제 수단인 신용카드는 1인 다카드 보유 형태이다. 따라서 신용카드 기업들이 무한경쟁에서 생존하기 위해서는 새로운 소비층으로 떠오른 실버층에 대한 적극적인 마케팅 활동이 필수적으로 요구된다고 할 수 있다. 따라서 이 연구는 고령화 사회의 진전과 소득수준 향상으로 실버층의 소비패턴이 크게 변화함에 따라 실버층 라이프스타일에 따른 신용카드 사용동기와 신용카드 선택요인들을 규명하고자 하였다. 그 결과, 라이프스타일 중 타인배려 요인이 신용카드 사용동기의 편의성에 유의한 정(+)의 영향을, 여가 요인은 신용카드 사용동기의 실속성에 유의한 정(+)의 영향을 미치는 것으로 나타났다. 그리고 선택요인에 있어서는 라이프스타일 요인 중 개성 요인과 유행 요인이 신용카드 선택요인 중 과시성에 유의한 정(+)의 영향을 미치는 것으로, 유행 요인은 경제성에 유의한 부(-)의 영향을 미치는 것으로 나타났다. 따라서 이 연구는 신용카드 기업들이 보다 효율적인 대고객 서비스 프로그램 개발과 마케팅 전략을 수립하는데 기초자료를 제공하고자 하였다.

Payment system is defined as the various contracts and operating facilities for the transfer of monetary value to clear the relationship between credit and debt. Payment systems essentially require the efficient and reliable operations. Card-based payment systems are developed practically and creatively in accordance with the progress of ICT. Especially in mobile environment with intelligent mobile devices such as smart-phones and tablets, a variety of payment services are provided. Existing card-based payment services are configured by the payment transaction initiated by the merchants card acceptance and then swiping into the CAT (Card Authorization Terminal) to begin the transaction. The merchant initiated payment services are now applied to the Wireless CAT (W-CAT) for mobile environment. That kind of payment services cause many problems such the illegal card information leaks and the lingering threat of W-CAT theft. Also, the use of many W-CATs increased cost to the merchant. In this paper, we propose the card holder initiated card payment system using the intelligent mobile devices in mobile environment for solving problems of the existing merchant initiated card payment system and coping effectively with the activation of a wireless data network and changes of information technology.

Korean Identification card or driver license is usually used to verify one's identity in Korea. These are also used as an adult certification. Since the form of these ID card is an analog and it needs to be checked with naked eyes, it might be used maliciously. Someone who's got someone else's ID card can do other things. Therefore, it must be reported rapidly when ID card is lost or stolen. The most serious problem might be occurred when they do not recognize and report the loss. They might suffer from pecuniary or mental damage such as opening a mobile phone service, providing loan or credit card, opening a personal checking account, etc. Thus, this study suggests and compares the ways of avoiding these problems. First, the most effective way is to send the authorization code via mobile phones in consideration of build-up period and cost. The person in charge of business processing department using ID card sends the authorization code via registered mobile phone. The owners submits it to the person and their identifications are confirmed. Next effective way is that the person in charge of business processing department using ID card sends text messages via registered mobile phone. Lastly, the most ineffective way is to introduce and implement the electronic ID card ultimately even though it is expensive and takes a long time to build up the system.

본 논문에서는 웹브라우저를 이용하여 로봇을 원격 제어한다. 4대의 독립된 PC를 사용하여 각각의 기능을 분리하고 상호 연동하는 구조로 PC를 연결하였다. 조작자가 시간과 장소에 제약받지 않고 웹 브라우저를 이용하여 제어값을 입력하면 제어값은 웹 서버를 거쳐 데이터베이스에 저장된다. 로봇과 연결된 PC는 데이터베이스에서 1ms 간격으로 제어값을 입력받아 제어값의 변화가 있을 경우만 제어값의 변화량으로 로봇이 동작한다. 스텝모터를 이용하여 간단한 로봇을 제작하고 이를 웹 브라우저를 이용하여 실제 동작시킨다. 조작자가 원하는 제어값이 최종 수신단의 로봇에 제대로 전달되어 동작하는지 확인하고 웹브라우저를 이용한 로봇제어의 가능성을 확인하였다.
