NFC is the acronym for Near Field Communications, and is a characteristic of many portable devices these days. The NFC can be a useful feature, and used. Many times it is not, although there is a promising future for the technology. In this article, we will examine NFC, what it is, how it works and what it is used. Then, you can also find out which devices have the technology.
What is NFC Technology in Mobile Phone?
The clue is in the name: Near Field Communications, or, in translation, Near Field Communication. The NFC is a set of standards for portable devices. This allows them to establish radio communications person-to-person (peer-to-peer), passing data from one device to another by touching them or placing them very close together..
The NFC has its origin in the RFID. RFID, or radio frequency identification, is the technology used by shipping companies, large warehouses and large stores to accompany the products. It uses electromagnetic induction to transmit information in a short space, so that, by simply scanning a container, a person can know what it contains. The NFC is a similar technology, but standardized for smartphones consumption. The standards NFC are defined by a group called the NFC Forum, which includes major manufacturers of consumer electronics. In essence, if your phone has NFC as a feature, it can be used to transfer data to other phones or to readers NFC.
This is all very cool. But is it useful? First, we will see the functioning of the NFC, and then we’ll look at more.
How it Works a Smartphone with NFC?
NFC is a means of sending data through radio waves. In this sense, it is similar to wi-fi or Bluetooth, but unlike those protocols (and like RFID), NFC can be used to induce electric currents within passive components as well as just send data. And is faster than the Bluetooth, in general. In fact, the two are closely linked.
NFC can work with passive devices that do not require their own power source, such as card readers. The transmission frequency of data of the NFC is 13.56 MHz. NFC can transmit data at 106, 212 or 424 Kbps (kilobits per second).
At the time of the writing of this article, the standard NFC has three modes of operation: mode peer-to-peer network that lets two smartphones swap data, a read / write mode in which a device active take information from a liability; and emulation of the card, in which an NFC device such as a smartphone, can be used as a credit card without contact.
There are some security issues with NFC, but they are manageable, if not minor. On the one hand, if someone can get close enough to you with a NFC reader, they can read the content from your NFC-capable device. It can be difficult to that happening but still, it is a concern.
And there have been attempts to create applications that could steal your information. As with any software that you install, it is critical that you know exactly what you are getting. Google Play and, especially, Apple iTunes are very good at maintaining applications unpleasant. But you can never be 100% safe.
Perhaps the biggest risk to its security represented by NFC is that your smartphone is even more valuable. Put all your payment information on a device makes you even more vulnerable to this device being stolen.
Uses of NFC on the Mobile Phone
Then you already know what is NFC and how it works. But what it can do for you? Why do some smartphone users consider NFC as an important feature?
Well, as mentioned earlier, there are technologies peer-to-peer network where you can share a file or a contact by touching two smartphones. This is a little cool, but hardly a feature not to be missed.
More important is the potential to trade without contact. Imagine your phone being used as a card through the NFC? You can see the benefit. You can actually dispense with your wallet, although the dangers of losing your phone are intensified.
Unfortunately, at the moment, a lot is still in need of popularization. The Google Wallet allows consumers to store credit card information, and loyalty in a virtual wallet and then use an NFC-capable device at terminals that also accept transactions with NFC. Apple Pay uses the same seistema in the iPhones. However, these systems still need to become popular.
Other uses for NFC include tags, passive NFC embedded in posters and advertisements that offer additional information or bonus content in the same way that QR codes have been pushed several years ago. Maybe NFC is more popular than the QR codes.
Something that can be similarly culturally specific is NFC in toys. Some games manufacturers have started to create figurines that contain NFC chips. In turn, they interact with devices that are running computer games. Then, you can create an augmented reality tool with your NFC device.
The smarter use of NFC is when it is embedded in a user process. Then, when you put your smartphone into a VR headset of the Google Cardboard, it is the NFC chip that tells the headset to wake up.
Focus on the future other potential uses for NFC include the ability to control devices around your home. Maybe your house unlock and the heating and the lights turn on when your phone enabled for NFC spent by a sensor in the input. Currently, these resources are more typically controlled via WiFi, but NFC can be more secure and require less power. Marginally less power.
And there are potential social benefits: if everyone had smart phones are enabled for NFC, to exchange contact data would be pretty straightforward. Of course that may not always be a good thing but, for the most part, the benefits outweigh the risks.
NFC is Important in the Phone?
The ability to transfer contacts via touch is nice, but it is not important. But the potential for NFC is huge. In the final analysis, everything boils down to real-world applications. If ever you can use NFC to make your smartphone your wallet, travel card, and remote control of home automation, wait for it to be in all phones. And, so that payments by mobile phone become more popular, the NFC will be a great resource.
Which Phones Have NFC?
If you have a smartphone top of the line, chances are the device has NFC as standard. But you can be sure to check the definitive list of devices compatible with NFC web site NFC World. You can also search on Google for “(NAME OF DEVICE) technical specifications” to determine whether the device has NFC.
