What is Near Field Communication (NFC)?

Near Field Communication a.k.a. NFC is a technology which allows two devices to transfer small amounts of data when they are kept a few centimetres away from each other. This is the technology used in some modern day services like Google Wallet and it is many times used for making purchases without a credit card.

Nowadays the NFC technology is in-built into some smart phones in a NFC chip which when tapped on a NFC reader can make purchases, use coupons by downloading the coupon onto the NFC device before making the purchase.

NFC although a great technology will take a lot of time to become a part of our daily lives as NFC is only compatible with devices that have the NFC chip in them which is there only in some smartphone today. Also required is a NFC reader in stores so that they can make the transaction possible.

NFC is built into the Nexus S 4G so it can pay for bills without using a credit card (although it is needed), wirelessly.
