Technology Analysis: Near Field Communications
Modern technological advancements have offered various tools for businesses while disrupting the traditional ways of doing business. One of the technologies presenting an opportunity for businesses to enhance their competitiveness is the Near Field communication, the aspects of which form the discussions of this paper.
The Technology, Its Features, and how it Works
Near Field Communication (NFC) provides a platform for data exchange between electronic devices that are at a distance of up to10 cm (NCF forum, 2012). NFC is a wireless communication technology that not only supports data transfer but also provides safe communication in transactions since devices disconnect once one moves out of range (Pesonen & Horster, 2012). NFC devices are used in applications such as contactless payment, mobile ticketing and interactive smart posters (Toegl & Hutter, 2011). Other potential and current uses of this technology in society includes accessing public transportation and facilities, retail transactions, and transferring personal data (NCF forum, 2012).
One defining feature of NFC is its ability to enable data acquisition only by contact to an object that has an integrated NFC-enabled reader (Toegl & Hutter, 2011). Readers may be integrated into devices such as mobile phones and digital cameras to allow these devices transfer information to other enabled devices within the 10 cm radius (Toegl & Hutter, 2011). The transfer of information between the reader (initiator) and the target device is either via passive or active-communication modes. In a passive mode, the electromagnetic (EM) field generated by the reader powers the targeted device thus allowing a bidirectional sharing of information (Toegl & Hutter, 2011). This saves power since both devices do not need to be plugged to a power source. In an active communication, both devices generate EM fields alternately, hence both devices need to be plugged to an active power source (Toegl & Hutter, 2011).
