NFC or Near Field Communication is the name of a technology that you have heard a lot about recently. Despite its arrival in our lives a few years ago, it is not until now that the NFC system on Android devices begins to spread among users.
Although its use may carry some risk than another, the NFC has come to stay thanks to the comfort it offers in its multiple functions. The best known is that of payments, which allows you to use the telephone as if it were a bank card to pay at any establishment. Nevertheless, the NFC is used for many more things, and we are going to explain them to you.
5 things you can do with NFC on Android
Read your electronic DNI (DNI 3.0)
After the change from electronic DNI to DNI 3.0, you no longer need a USB reader to carry out procedures with public administrations. As we explain in , you can use your mobile as a reader of the DNI 3.0 as long as it has NFC technology. After confirming this detail, you must download the app “DNIe Reader for PC, using the mobile phone” on the phone and the DNIeRemote program on the computer.
Once both tools have been downloaded, you just have to follow the steps indicated by both to configure the DNI 3.0 on your mobile. After completing the process, just bring the back of the mobile terminal closer to the DNI so that it reads the chip that it carries and the identification is carried out in the procedure that you are going to carry out on the computer.
Strengthen your privacy with USB / NFC security keys
Using online services every day poses a risk to your security and privacy, since you share an endless amount of personal information that must be kept that way, personal. To strengthen your presence on services such as WhatsApp, Twitter or Facebook, you have two-factor authentication, which adds a layer of security when logging in, that is, you will need another factor in addition to the password.
One of those factors may be a USB security key like Google’s Titan Security Keys, which also has NFC technology. When you log in to one of your accounts with your mobile, in addition to entering the password, you must bring the key to the back of the phone so that it, NFC using, recognize that you are the one who wants to access and not an impersonator who has discovered your password.
Connect your mobile with your headphones with just one touch
Connecting your mobile with other devices that have NFC is extremely fast, which makes it stand out from connectivity such as Bluetooth. Manufacturers typically integrate NFC technology into their products to facilitate a one-touch pairing.
For example, if you have a Speakers or headphones with NFC, just put them together to the back of the phone so that the connection between the two starts and you can listen to your favorite music without having to spend a few minutes to pair both devices.
Share files with other users
One of the most prominent functions of NFC technology is to share files with other users more immediately than via Bluetooth or Wi-Fi. To do this, simply enable NFC on both phones, access the file we want to share and bring the two terminals closer together (at a very short distance, yes).
Automatically, the transmission process will begin and the receiver will only have to accept to receive the file in question. Without having to establish a previous connection between the two devices, data transmission via NFC is a more comfortable method than others that we usually use.
Configure your own functions using NFC tags
We cannot talk about NFC technology without referring to its labels, devices that you can configure yourself so that they fulfill the functions you want. First of all, you should get hold of these labels, widely available in online stores.
Afterwards, you must download an application such as NFC Tools (there are more in the Play Store) for tag management, which is what will allow you to program them so that perform certain actions on contact with your mobile. For example, you can place an NFC tag on the bedside table in your room so that, when you put your phone down, it goes into do not disturb mode while you sleep.
NFC tags give you multiple possibilities, so it is best that you try them and discover the applications that can give you the most. As you have seen, just by bringing your mobile phone closer to the DNI, other devices or a tag, the NFC opens you to a world of options that go beyond mobile payments.
