You must have come across the term NFC a lot recently in case you read technology news. NFC is still in its fairly early stages, but analysts have forecasted it could have a significant impact on the cellular phone industry. Before you can appreciate the breadth of its potential impact, however, you must understand the answer to the question: what is NFC?

Near Field Communication

Near Field Communication is typically abbreviated as NFC. NFC is a sort of short-range communication available in cell phones, credit cards, and some other gadgets. Whilst the latest technology is concentrating on increasing the range of communication, near field communication (NFC) takes the contrary approach. NFC communication occurs only over very short distances.
It has been done intentionally for a reason. NFC is for the communication of private information. Thus the limited range offers the user with security against spying and eavesdropping when information is being exchanged between two parties. Eavesdropping can happen with N.F.C. only if the eavesdropper is in close range to the gadgets. This makes interactions using NFC inherently safer and private.

How Does It Work
We’ve given you a general answer to the question, what is NFC? but haven’t explained how the technology actually operates. It is really an easy technology to setup and use. In this mechanism one device acts as a sender of radio wave signals and the other device acts as the recipient. After developing a connection between the two gadgets, data can be transmitted continuously between them. One or both devices can send out information.

What Is NFC Used For?
The greatest impact NFC will make is going to be on the cellular phone industry. Supporters of NFC claim that by advancing this technology a bit more, it can be used in future for allowing cell phones to become a virtual wallet. NFC could be used for storing debit card numbers, ticket numbers, and reward cards on the phone, thus eliminating the need for carrying a wallet. You can find NFC equipped cell phones in the market and there have been good trials of using NFC to make purchases and use mass transportation.

Are There Any Problems?
There are a number of possible uses of NFC, and only time will tell how effective use of the technology is. The major question surrounding NFC, however, is regarding its security. Despite concerns about transmitting private information over NFC, security experts attest that NFC is safe as long as somebody isn’t standing irritatingly close to you while you use it.
There have been other obstacles to widespread use of NFC. For example, when the iPhone5 was released, Apple chose to leave the NFC chip out of its phone. The reason behind this was that they planned to make their phone slim and light, however, adding an NFC chip was increasing the weight and size of the phone. Another reason behind not putting NFC chip was that apple considered that many people are not yet ready for this mode of communication.

So, the answer to the question what is NFC? is multifaceted. It is a new technology that will impact the way we communicate and do business. It is still riding a bit under the mainstream radar, however, if and when we will see this technology on a large scale is yet to be determined.
