Credit cards, movie tickets, train tickets and all similar passes are soon gonna disappear. Welcome Near Field Communication (NFC), the stylish wireless technique that could be already in your smartphone. NFC is predicted to be a de facto standard in mobile payment technology. Hence, most of smartphone manufacturers are adopting it.
Many Android devices and some Blackberry smartphones have already NFC chips within them. Apple has ignored NFC. So, if you are a fan of the fruit company, then you still got to wait.
Lets learn about the NFC technology before knowing the NFC applications.
What is NFC and How it works?
NFC is a short-range (high frequency) and low power wireless technology. It require the devices to be closer by few inches (typically a distance of 10cm or lesser ). It offers a data rate of 424 kbps and hence not advisable to use it when data transfer required is greater than 0.5Mbps. The short-range characteristic ensures security as eavesdropping is difficult in such a scenario. Unlike Bluetooth, it doesn’t require any pairing codes.
NFC chip is quite similar to RFID chip. NFC technology makes use of “Inductive Coupling”. When a NFC equipped smartphone comes in the proximity of a NFC chip, a current is generated as the chip is surrounded with a magnetic field. This current signal is the actual short-ranged signal which is employed in NFC technology.
Here, goes the list of top NFC applications.
NFC as a payment method:
NFC is gradually becoming a mainstream payment method. NFC can trigger a payment using Google Wallet. Contactless payment cards have been always considered as really cool technologies. NFC mobile payment is still not popular. Somehow, it yet haven’t replaced the traditional payment methods and in most places, it is still in trials.
NFC in Event Ticketing
As afore-mentioned, soon bus passes and movie tickets are to vanish. NFC enables an easy way to ticketing. Buying tickets and ticket verification steps is soon to be a matter of a few seconds with the help of NFC equipped phones and NFC enabled payment counters. NFC equipped phones and stickers can be used as a means of identification. Many cinemas and park metering services have already made use of this amazing technology.
Initiation of transfer data between mobile devices
NFC as a trigger to activate file transfer between two smartphones is the most common use of NFC. For phones without NFC chips, there are alternatives like BUMP. For file transfers, NFC serve as a medium of authentication. Once verified, the devices switch to high data transfer technologies like Wi-Fi or Wi-Fi Direct.
A NFC phone can be used to unlock the door of your house or to unlock your car. It can also be used to turn on computer. You can get the details for turning on a computer using NFC chips at this link. You can also use NFC stickers to change settings of your phone by a mere tap to these stickers. For example, by a tap you could make your phone into “customized car mode”.
Interaction with Smart iCards and Posters
Have you heard about “NFC business cards”? Yes, your business card could be embedded with a NFC chip. So, it can tell you more details than you could print in a card. The details might include links to your social media profiles and may be even a CV. Doesn’t it sound really cool. If NFC becomes so common, then may be it could replace the barcodes and QR codes. And, with NFC you no longer have to hand over the card. Instead, by a tap of the v-card the other person will get your contact details stored in his/her phone.
Share your Wi-Fi password
We tend to use long and complex passwords for Wi-Fi connections. So, it is always quite a tedious task when it comes to sharing the password to some guests at your place. The simple solution is to write the Wi-Fi password to some NFC chips and hand these chips to guests when they come to your home. The drawback is we expect the guest to have NFC equipped smartphones with a NFC reader app installed in it.
A request to wireless tech enthusiasts who own a NFC occupied smartphone
If you are having a smartphone with NFC, consider buying some tiny NFC tags and start making use of NFC feature. Download the app Trigger (or some similar app) and program the NFC tags . NFC tags are really cheap and they can be bought online from ebay for less than 5 USD.

So I hope now you finds NFC is a cool technique after reading this post on “Top NFC Applications”. People insist its a cool technology. So if you are living in a country where NFC is still not popular and anticipate that “One day, you will find it useful”. I am a fan of videos from Marques Brownlee. A video can inspire you more than a simple blog post. See his video (given below) about NFC where he explains the NFC applications you can make use if you have a NFC enabled smartphone.
