NFC, it's an acronym that we've been hearing more and more about in recent years and above all a technology that is starting to make its way into our everyday lives more and more.

Yet, despite the fact that this data transfer technology is more and more popular and used in many areas as we will see in this article, it is still quite mysterious for a lot of people.

Indeed, although we have all more or less heard of this technology, we do not really know what it is used for. For some, it is completely obscure while others know a few points such as the fact that it helps with contactless payment, for example.

In this article, we will therefore come back together to the main points to know about these NFCs and especially what they can be used for in the case of our telephones mobile under Android like the Samsung Galaxy for example which embeds this technology via functionality Android beam.

What is NFC technology?

NFC, Near Field Communication, is a technology allowing data to be exchanged within 10 cm between two devices equipped with this device.

This is a very simple method to transfer files between two smartphones Android (photos or videos for example), provided that they both have NFC technology (short distance wireless data transmission).

There are multiple uses of NFC: a smartphone can connect to a computer to download a file, a television will exchange data with a smartphone, etc.

How do I know if my mobile phone is NFC compatible?

It's true that before going further in the explanations, particularly on what you will be able to do using this technology, it is important to know if your mobile phone is NFC compatible.

To know this, you have several means. Indeed, the first is to go in search of the program Android beam in the features of your phone, it will then indicate that your phone is compatible.

As we told you earlier, the mobiles of the Samsung Galaxy range are basic NFC compatible for a while, so you will have few doubts if you have a recent mobile in this range.

Finally, you can always check the internet to find out if your phone is compatible. In fact, you will simply have to type its model accompanied by “ NFC-enabled?” and you will have your answer in seconds.

How to use NFC on Android ?

To start, check if the NFC function is activated on your smartphone. To do this, go to the Settings section.

Now you are ready to share a file. The principle is simple, you must go to the gallery of your file explorer. Where the file to share is located.

Now place the two devices back to back (be careful, you only have a few seconds). As soon as the two devices come into contact, they emit a vibration.

Once the link is established, the device receiving the data displays a notification. Simply accept for the transfer to begin.

It's simple, in the blink of an eye you can transfer files by bringing the two NFC smartphones together.

Other uses of NFC technology

As we have just seen, NFC technology is a data transfer technology, but as you can imagine, this is obviously not limited to transferring a few photos between two mobile phones.

NFC technology in identification

NFC is also a communication technology with an external body that can be used for a lot of things and for example to make identification and confirm your identity in seconds.

Let's take an example, that of bus cards or more generally subscription cards that you must scan each time you enter the place where you are subscribed. Well, NFC technology is used very often.

Therefore, once it becomes popular, you will only need your SIM card and your NFC compatible phone to be able to replace all this type of card in your wallet.

Knowing that you always have your cell phone with you, this will definitely be very practical and you no longer risk having the classic problem of forgetting your card in your pants pocket that you had yesterday.

Pay with your mobile phone

Being able to replace all your cards is good, but what if we told you that you can turn your phone into a bank card with Android beam and NFC technology, would you believe us?

Well, yet it is the case and you also use this technology on your classic payment chip card via a technology which has become enormously popular in recent years, contactless payment.

In fact, it's quite stupidly a transfer of data between your bank and the organization to which you make a payment and it uses NFC technology. From then on, we quickly understand how we can transform our laptop into a mobile terminal.

To do this, some banks already offer services allowing you to save your payment methods directly on your mobile. From then on, here again, you may soon only needa SIM card so you can do your shopping and no longer need to carry around cards.

This is one of the great strengths ofAndroid beam is to ensure that today's telephones are much more than a communication technology. Indeed, soon, these phones could be used to centralize all your contactless payments, whether subscriptions or even traditional payments which were previously made by bank cards.

Moreover, with the development of NFC technology, there is another technology that could disappear, that smart cards. Indeed, the NFC makes it possible to bypass it completely, so to see how this will evolve in the years to come and if your phone will continue to concentrate all these services in addition to its communication technology.
