What is NFC?

NFC technology described on abbreviationfinder has evolved to quickly facilitate the way in which we live with technology and although at the beginning it was a feature of high-end phones, today by hor is on phones of middle and low range of Sony, Motorola, Samsung, Lenovo, LG, Huawei and others brands competing in more accessible telephone market. Such is the boom of this technology that even Apple finally integrated the iPhone 6, although in reality in this work in a limited way, since while other smartphones let you use it for the exchange of information, in the iPhone was installed specifically for a mobile payments system. But to better understand its mechanism you answer the following questions.

What is NFC

What means exactly?

Let’s start with the basics. The initials refer to the term Near Field Communication, which is something like “near field communication”in Spanish. Since its transfer rate round 424 kbit/s, its role mainly consists of the Exchange of instant information between devices when they are very close, unlike the Wi-Fi or Bluetooth, allowing you to be even in different rooms and transmit large amounts of data.

How does it work?

Explained in the simplest way, all you have to do is activate the NFC function and put together two devices to connect just the height of where are the NFC chips – phones usually placed in the rear, beneath the housing. in computers, regularly on the side of the touchpad-.

What will happen in that time is that using a technology that is derived of them principles of RFID (identification by radio frequency), them phones or gadgets begin to transfer data between itself, although specifically for NFC the field is very reduced, by that have that gather them teams all the time during the transmission of data. This also helps to increase the security of exchange of information and thus prevents that you connect to devices that does not want to.

What is NFC 1

This technology integrates tags with a chip and a transmitter antenna. There are two types of RFID tags: Active, referring to when two devices constantly emit transmissions and need power, and passive, which are activated only in the presence of a reader (e.g. a phone or a tablet).

Which devices are NFC?

Although most relate this technology with smartphones, also is present in televisions, speakers, headphones, tablets and consoles. And although at the beginning tags that allowed use this function were very expensive, the idea is that all computers have it in the future, just as it was adopted to Bluetooth as a basic feature.

The brands that most have explored the use of this resource in their phones are Samsung, Motorola, LG, Sony, HTC, BlackBerry and Nokia.

Why have NFC?

The possibilities provided by this tool are very broad and different industries around the world, are using it as allows you to establish a very personal communication with users of different services. In this list you will find them uses more common that is you have given until now, some of them already them use in Mexico, others are available only in a couple of countries and others still are a project without much success.

What is NFC 2

It is already possible:

-Transfer photos, URLs or documents from device to device.

-Synchronize a phone with a loudspeaker or headphones for audio transfer through the automatic activation of Bluetooth ports.

-To display quickly in the TV the content that have in the cell.

-On prints, you can assign specific tasks to the phone. For example, paste a label with NFC in the entry of your House and when approach the phone, this active automatically the “mode home”, which turns on the Bluetooth, low the brightness of the screen and begins to play music, all without have that activate function by function. Many cell phones already include several ‘modes’ preset in the phone only have to activate and which can be customized easily. NFC tags often are purchased separately and the most famous are the of Sony, but LG came to include labels with some of their models.

Even as a project in several countries:

What is NFC 3

-Use your phone as a credit card to make payments in shops or even to upload to public transport.

-Receive information about products in the stores directly to the cell.

-Make Check-in in some establishments without having to manually search the place in which you find yourself.

-Access to the room of a hotel, without the need for keys, just have to synchronize with the phone information of the host.

-Share your home Wi-Fi password via NFC tags.

So in short you should stay with two main ideas: the NFC is a short-range communication system that saves so much time, as an effort to synchronize two devices. And Although in practice are the plans that you have for this technology that what in fact is currently used, still working a day is on almost all phones and people use them as a method of identification and mobile payments.
