Yayın NFC loyal: A Beneficial model to promote loyalty on smart cards of mobile devices(IEEE, 2010) Özdenizci Köse, Büşra; Coşkun, Vedat; Aydın, Mehmet Nafiz; Ok, KeremNear Field Communication (NFC) as a new emerging technology currently tries to find a suitable ecosystem. Development of new standards such as secure element, secure channel, as well as Java Card enables creating new ecosystems using a concurrent multi application platform based on Global Platform. We proposed NFC Loyal, which maintains data interaction and data sharing among payment and loyalty applications through our proposed structure, called as Secure Common Domain Management System (SCDM). SCDM as a centralized database management system on the smart card stores valuable iriformation provided by payment applications and shares them with loyalty applications. The direct outcome of using NFC Loyal is the increase in repeat purchases of customers; as well as a business plan among the payment firms, loyalty firms, and the smart card owner. We fully describe the technical including security architectures and background for the SCDM, and explain the details of the proposed model.Yayın A role-based service level NFC ecosystem model(Springer, 2013-02) Ok, Kerem; Coşkun, Vedat; Özdenizci Köse, Büşra; Aydın, Mehmet NafizNear Field Communication (NFC) is a short range wireless communication technology allowing to communicate mobile devices within close proximity. It provides opportunity for service providers to offer various value added services to customers. NFC technology allows the usage of wide range of applications and eliminates the obligation to carry additional components other than the mobile device such as credit or payment cards, tickets, identification cards or keys. Despite its technological advantages over alternative ones, the NFC business ecosystems and services are yet to take off. The problems mainly arise with the business issues triggered by different and mostly conflicting needs of many actors in the ecosystem and several additional technical issues. In this study, by adopting a role-based service ecosystem modeling, we propose an NFC ecosystem model which perfectly specifies the roles in the ecosystem, and defines set of activities for each role, and communication structure. We analyzed NFC ecosystem in three phases as pre-installation, installation, and service usage. We have defined the activities and communication structure in the first two phases, and finally investigated the service usage phase in three different operating modes of NFC. After giving the details of the proposed ecosystem model, two use cases are given to validate the developed ecosystem model. We complete our study by discussing the requirement satisfaction.Yayın Current benefits and future directions of NFC services(IEEE, 2010) Ok, Kerem; Coşkun, Vedat; Aydın, Mehmet Nafiz; Özdenizci Köse, BüşraNear Field Communication (NFC), as an emerging and promising technology, is an integration of Radio Frequency Identification (RFID) technology with mobile devices. NFC-enabled mobile devices can act as contactless smart cards and are also capable to read and write data from/to those cards. Research endeavours concerning NFC appear to focus mainly on development of NFC enabled services and applications. On the other hand, benefits and underlying values associated with different NFC applications' service is not yet well elaborated. In this paper we examined existing NFC applications, prototypes and studies from both academia and industry. We analyzed these applications by classifying them into NFC operating modes to surface the nature of underlying value-added services and benefits that they provide. Moreover we emphasized possible future usage scenarios together with directions and questions for future research based on the identified benefits.Yayın How do mobile technologies affect work and private lives? The case of Turkish banking professionals(IEEE, 2014-07-27) Yıldırım, Nihan; Ansal, HacerMobile technologies (MTs) became important part of infrastructure in service industries. The impacts of MT usage in work are shown to be significant; improving the productivity, responsiveness, effectiveness and flexibility of companies, while reshaping the work place organization and making employees accessible on a 7/24 basis. However, there are great differences in terms of the types and levels of these impacts on organizations and individuals as the industry, region/country changes. Moreover, not much is known about the effects of MTs in developing countries like Turkey where there is a rapidly increasing mobile penetration (mobile phone and internet subscription rates) which is a critical infrastructure component of mobile working.Turkey has quite an advanced banking industry that has went through serious industrial restructuring. Banking industry has always been among the early adapters and first users of new information and communication technologies, as well as first appliers of new organizational development and human resource management techniques. In the last few years, mobile technologies has become key technologies for banks and accordingly, the usage of mobile devices by banking professionals for work purposes increased. As happened in other new information technologies and human resources systems, experiences of banking industry in mobile technology usage at work-place can provide best practices or lessons for practitioners form other industries.This study tries to provide insights on the perceptions of employees in the Turkish banking industry, about the impact of these technologies on their work practices and on their private lives. A structured survey is carried out with 107 white collar professionals from 5 major retail banks in Turkey. By conducting Factors Analysis and correlation analysis, 8 main factors are identified that represents the impacts of MT usage for work purposes and their interrelations with eachother and demographic factors are explored.Findings reveal that intensity of mobile device usage is still not high in banking industry. Employees perceive the positive impacts of mobile working on information and knowledge supply chain, time management of their organization,. Time management is one of the issues occurred due to mobile working. Attention and focus on meetings and interviews seems to be challenged due to parallel usage of mobile devices in meetings. There are correlations between feeling "Control, pressure, demand for responsiveness and workload" and intensity of mobile device usage and continous accessibility. Similarly, improvements in information and knowledge/flow and meeting organizations are correlated to the impacts of mobile working on productivity, quality and work-life balance. Research showed that the perceptions of employess about the implications of mobile work on "productivity, effectiveness and work-life balance" and "Attention and Focus on Group work like Meetings and Interviews" vary by gender, and on "Multitasking and work-shifting" vary by age. Education level also affects the perception on "Productivity, effectiveness and work-life balance". Hence the policy makers and managers and they also must consider the demographics of the employees when designing and implementing systems about mobile working in banking industry.
