What is Near Field Communication?

Near Field Communication (NFC) allows wireless and short-range (10 cm or less) data transfer between supported devices such as tablets and smartphones.

Overview

What it is: Near field communication (NFC) allows wireless and short-range (10 cm or less) data transfer between supported devices such as tablets and smartphones.

What it does: NFC uses either active or passive devices for the transmission and receiving of the data signal. Passive devices use small transmitters such as tags for sending data and do not need a power source. Active devices liaise with passive devices and each other and receive and send data. It allows maximum privacy and is affordable.

How it works: An NFC chip uses radio waves and electromagnetic induction phenomenon for wirelessly sending data. It deploys Tesla’s wireless power transfer concept for communication. NFC sends current from the solenoid in the sending device to the coil in the receiving device through inductive coupling. NFC does not need the internet for two-way communication.

Why it matters: Industries with applications using persistent communication with tags at their process points can reduce costs, by deploying NFC based phones rather than the traditional handheld readers. NFC also controls forgery by providing product authentication, manufacturing control, and tracing and tracking of applications securely and reliably. When embedded in products, NFC can provide a unique ID, allowing tracking from manufacturing to consumption, and data gathered can be shared via the cloud.

What to do about it: Understand the numerous applications of NFC and review existing processes oriented around physical items or locations, to see whether NFC might create efficiencies or new opportunities for your enterprise. to better serve customers and support business objectives. Consider deploying this technology to provide more convenience and secure payment choices to customers and to improve customer experience.
