    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, Kerem
    Near 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.

    A role-based service level NFC ecosystem model
    (Springer, 2013-02) Ok, Kerem; Coşkun, Vedat; Özdenizci Köse, Büşra; Aydın, Mehmet Nafiz
    Near 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.

    Current benefits and future directions of NFC services
    (IEEE, 2010) Ok, Kerem; Coşkun, Vedat; Aydın, Mehmet Nafiz; Özdenizci Köse, Büşra
    Near 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.
