How about this, no paperwork, no train or bus tickets, no more receipts just a single swipe through your mobile and everything is paid. That's what we call NFC, i.e. Near Field Communication. Unlike Blue-Tooth or Wi-Fi, it doesn't require pairing with any other device. This is a simple technology, which works within a short range. NFC is much more similar to RFID, but we can say that it is an extended version of RFID, but the difference is that RFID waves can be used for long ranges, but the NFC is limited to communicate within 4 inches. Basically, NFC is a high-frequency wireless technology, which allows two-way communication without pairing the devices. It is also known as "Mobile Wallet", as it has the capacity to replace your credit cards and cash. With the help of NFC, one can pay for groceries; can even pay bills online with just one tap or swipe on your phone.
What are the benefits of NFC?
NFC is just like Google Wallet, where you can store your debit cards or credit cards and you will get a virtual Master card, using which you can pay your bills. Through NFC, one can pay their bills wirelessly or can even use their mobile as an electronic travelling ticket on existing contactless infrastructure, which is already in use for public transportation. It allows users to share their content between digital devices. The user doesn't need to perform manual configuration for identifying devices. NFC took some seconds to establish connection between devices. This technology provides more security for some particular applications like paying an online bill; secure logging in at any location. The shorter range of NFC helps user to provide higher security, if compared to Blue-Tooth or Wi-Fi. It is also convenient to use NFC at crowded places.
Well, the NFC is available in India also. Nokia, Samsung, Sony has already introduced NFC in some of their smart phones, but it doesn’t count as a necessity here.
