what is the use of near field communication
Near-field communication NFC devices are used in contactless payment systems, similar to those used in credit cards and electronic ticket smartcards and allow mobile payment to replace/supplement these systems. This is sometimes referred to as NFC/CTLS (Contactless) or CTLS NFC. NFC is used for social networking, for sharing contacts, photos, videos or files.[2] NFC-enabled devices can act as electronic identity documents and keycards.[3] NFC offers a low-speed connection with simple setup that can be used to bootstrap more capable wireless connections.[3]
Communication studies Communication studies integrates aspects of both social sciences and the humanities. As a social science, the discipline overlaps with sociology, psychology, anthropology, biology, political science, economics, and public policy.[5] From a humanities perspective, communication is concerned with rhetoric and persuasion (traditional graduate programs in communication studies trace their history to the rhetoricians of Ancient Greece). Humanities approaches to communication often overlap with history, philosophy, english, and cultural studies.
