What Is NFC?


NFC is a technology that is becoming more and more popular with each single passing day and many people are keen to know about it. There are numerous tablets and smartphones having this technology but still people don’t know much about this technology. You may have heard about Apple pay, it is the digital wallet for iPhone, Apple Watch and other products offered by Apple. It is making its way into hundreds of thousands of online retailers and stores. But you may not know about this technology, the uses for it, or why we should care.

The fact is that this technology is more than a wallet replacement. There is nearly endless potential when NFC chips are involved. This article will be helpful to answer your questions regarding this technology.

What Is NFC?

NFC stands for Near-Field Communication and it allows laptops, tablets and phones to share data with other devices that are having this technology. This technology works on the principle of radio frequency identification known as “RFID”. RFID is a technology that is widely used to scan those security cards that get you into the office every day.

Near-Field Communication technology is almost same to the RFID, but it is limited to communication within a specific range of four inches, which is why you have to hold your phone too close to the contactless reader in case you are using Apple or Samsung Pay.  Many people consider this small radius a major benefit and it’s one of the reasons that why this technology is taking off as a secure alternative to credit cards. This technology can also be used to share data like videos, pictures, contact information and photos between two devices.

How Does It Work?

Unlike Bluetooth technology, it doesn’t need any kind of manual pairing or device discovery in order to transfer data. With the help of this technology, a connection is automatically started when another device enters into the range. Once in range, both the devices instantly communicate and send prompts to the user. It has a huge potential in future. Here are three major ways how this technology is working between devices.

Digital Wallet:

Placing your smartphone within the range of the Pay Pad or contactless reader will prompt your passbook or wallet and then it will ask you to confirm payment. If you are using Apple Pay, you will have to place your finger on the home button which will identify your Touch ID. It also works with Samsung Pay and Android Pay.

Sharing Between Android Devices:

When two NFC enabled device are in range, you can easily share your desired content (pictures, videos, or contact information) with other device with the help of Android Beam. Android devices have been able to use Android Beam for a while now, but this feature is little-known by users.

NFC Chips:

These “taps” can be programmed with certain apps to perform certain tasks upon scanning. For example, if you can put one on your desk and with a quick scan upon tapping, you can set your phone on vibration, enable/disable work related notifications, or disable GPS, among other features.

Which Devices Have This Technology?

Apple’s smart phones from the iPhone 6 and iPhone 6 Plus onwards additionally have this technology, as do the Apple Watch and Apple Watch 2, yet with limited use until now, as it’s usable for Apple Pay.
Whereas, Android smartphones have been using this technology from a long time and finally the people who are interested in Microsoft’s Windows 10 Mobile will have the ability to use Microsoft Wallet, however right now this is just accessible in the US.

Why NFC-based Payments Are Secure:

The most important step in the mobile payment transaction is the secure element, which holds all the approval power. Though it’s a chip in the phone, or functions virtually with the help of cloud technology, the secure element is tamper-proof and is protected by a unique digital signature. You can pay easily on a single tap with the help of your phone and you don’t have to worry about any theft or scam. NFC based payments are more secure than swapping your card on a machine. Well, you can say that this technology is a ticket to the future. Everyone knows the risks that are associated with credit cards but with the help of this technology, you can easily avoid such scams that you or your friends have encountered in the past.


All in all, the unique information on your frequent shopping loyalty cards, library cards, business cards and so on will be contained and transmitted basically by means of Near-Field Communication technology. Officially may such cards are being digitized and you are invited to a new future now. This technology will totally change the way you pay online or in local markets.
