This study is meant to derive what is needed to enhance the convenience and satisfaction of users of mobile credit card applications. For the first step, the current status of simple payment service using application has been identified and in-depth interview by reorganizing Peter Morvile's Honeycomb model into the five usage principle based on the main function of the application card. As a result, it was found that users prefer personalized services that fulfill the purpose and key functions of the app card and take into account their consumption patterns rather than too many additional functions. Based on this study, it is expected that it would help card companies increase their experience with app card users and strengthen their platforms.

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.

현재 명함교환 App은 Bluetooth, QR, NFC 등의 기술을 이용하여 연락처 정보만 교환하는 방식이다. 이는 컴퓨팅 오브젝트의 저장 공간이 매우 한정적이기 때문이다. 본 논문에서는 마이크로 웹페이지를 이용하여 연락처 정보와 디자인을 고려한 이미지까지 사용가능하도록 하였다. 연락처 정보와 디자인을 위한 템플릿 정보를 함께 압축하여 저장 공간의 효율성을 높이고 개인의 특색에 맞는 명함 디자인을 교환하는 방식이다.

In May 2014, AppCard(Which is a smartphone application designed to register and use a credit card in a mobile phone by credit card company.) was attacked by smshing and a vulnerability which could not obtainable phone number. After that, credit card companies have supplemented and operated by introducing additional authentication methods to supplement the vulnerability. However, The analysis of the authentication environments, purposes and methods is not enough to lower the level of vulnerability and risk from existing accidents. This study analyzes the authentication process of the AppCard in the electronic financial service by applying the NIST's authentication guidelines, identifies the problems and suggests improvement directions. The method analyzed in this study can be applied to the analysis of the authentication method in addition to the application card, so that it will be highly utilized.

Currently Plastic Student Identity Card has not been used frequently because it is inconvenient to possess. In this paper, we propose and develope Mobile Student Identity Card(MSIC) which consists of combination of smart phone and student identity card to support convenient campus life for students in school. The main features of the developed MSIC are as follows. First, it can confirm student identity and offer MSIC to each students by using Database. Second, it can support convenient campus life for students by adequate layout. In the performance evaluation, we use development kit based on Android and AVD(Android Virture Device) for simulation.

Among the various services for mobile banking, user authentication method using bank security card is still very useful. We can use mobile banking easily and safely in case of saving encoded security codes in smart phone and entering codes automatically whenever user authentication is required without bank security card. In this paper automatic recognition algorithm of security codes of bank security card is proposed in oder to enroll the encoded security codes into smart phone using smart phone camera. Advanced adaptive binarization is used for extracting digit segments from various background image pattern and adaptive 2-dimensional layout analysis method is developed for segmentation and recognition of damaged or touched digits. Experimental results of proposed algorithm using Android and iPhone, show excellent security code recognition results.

According to popularization of smart phones, we can easily see the QR code attached to products. Restaurants also provide customers with store information using QR code. Sixteen years have passed since QR code was developed. In Korea, QR code has been widely utilized in the field of marketing because of easiness of technique implementation and channel expansion to mobile. However, to recognize QR code, we should run the proper application and focus on it during loading time. To address this problem, this paper proposes the app to manage store information using NFC technology. The proposed app saves easily store information through the name card of a store and facilitates its management obtained by a smart phone.

본 논문은 효율적인 명함 교환을 위하여 NFC를 활용하는 어플리케이션을 개발하였다. 기존의 오프라인 명함은 사용할 때 발생하는 제작비용과 보관상의 어려움이 있다. 이러한 문제점들을 해결하기 위해 개발한 프로젝트는 자신이 사용할 명함을 스마트폰에서 제작하고, 스마트폰에 기본적으로 탑재되어 있는 NFC 기능을 활용하여 명함을 교환하는 App이다. 사용자간 명함교환은 안드로이드 OS에 기본 탑재된 Android Beam 기능을 적용하였고 명함제작을 위해 스마트폰 카메라 또는 기존 사진 이미지를 활용할 수 있어 활용과 교환측면에 장점을 가져 활용성과 편의성이 용이하다.

The use of mobile payment services has recently increased in South Korea. Mobile payments allow consumers to purchase items digitally, using a mobile card in an app affiliated with a payment service. This study explores the predictors of intention to adopt mobile payment services. The study employed an A(affective)-B(behavioral)-C(cognitive) model with two antecedent variables: cognitive (perceived usefulness, perceived risk, perceived ease of use, and perceived herding behavior) and affective (satisfaction with the status quo, innovation resistance) responses. An online survey of 405 non-users of mobile payment services aged 20 to 49 years was conducted. The study used SPSS 23.0 for descriptive analysis and Amos 23.0 for confirmatory factor analysis and structural equation modelling. The results are as follows. First, perceived usefulness, perceived risk, and perceived herding behavior significantly influenced innovation resistance. Second, perceived herding behavior significantly influenced subjective norms. Third, innovation resistance and subjective norms significantly influenced the intention to adopt mobile payment services. The findings suggest that the A-B-C model can be useful in understanding consumers' adoption and resistance behaviors and that cognitive and affective responses are important antecedent variables affecting the decision to adopt mobile payment services.

Nevertheless 3D printer is propagated fast, it is difficult for us of using 3D printer at the same time because of 3D printer's slow velocity. Existing solution is to print using SD card which moves files and on PC but this method is spend too much time and can not be showed status of printing. Yet we have no 3D printer software solution which is controlled and printed remotely. Therefore, this 3D printer software solution makes 3D printer be connected on internet networks and selected to use it on smart App. And it is controlled and printed remotely. In my paper, to build an Android App. which can execute these functions, an effective analysis & design using UML and implementation method will be presented.
