Near Field Communication (NFC) technologies are normally used to establish radio communication between two NFC compatible devices by touching them together or bringing them together less than four centimeters. Nowadays, the interface of a large range of business and consumer applications are based on such technologies. In this paper, we propose a model to identify human-system interaction patterns that occur when NFC enabled devices are employed. Moreover, we show the applicability of such a model through an analysis of a relevant number of real world cases of applications and services which have currently arisen in many business streams. The study is aimed to categorize current NFC interfaces and to explore their underneath value.
