Surely you have seen the acronym NFC in the technical specifications of a smartphone, but do you know what it means? Today in our Android series for Beginners, I will explain what, what it is for and how to use this technology that has a promising future.
The acronym NFC stands for Near Field Communication, and refers to the technology by which information can be exchanged wirelessly between two devices close to each other. This exchange is done automatically, that is, without the need for previous configurations, and can happen between smartphones but also with any other device that has a compatible chip.
How it works?
Basically, the technology creates a short-range radio frequency link that can transfer small amounts of data between two devices positioned a few centimeters away. It differs from Bluetooth because it does not need pairing devices.
Even so, the technology is very safe and prevents the intervention of third parties in the referred data exchange. The types of data can be the most varied, but so far the technology has been more developed to streamline payments. I will show below, however, other very interesting uses of NFC.
The possibilities of exchanges are innumerable with two devices that have the NFC chip. Send photos by email if your friend is present, for example, a thing of the past. Just enable the function and bring both devices together. Your device will vibrate and the message Tap to send appears. By clicking anywhere on the screen, the photo will be sent.
Music for all tastes
Whoever has a speaker with NFC chip can choose the soundtrack simply by choosing the music on the smartphone and then bringing it closer to the speaker. The coolest thing that, in a meeting of friends, each one can be the DJ and choose the music, transferring it by the same technology.
As I said before, the possibilities are endless, and in my opinion, that should be the direction taken by Android and its new applications.
In addition to exchanging files, NFC can be the gateway to the world of mobile payments on services like Apple Pay, Android Pay and Samsung Pay. It is clear that on some platforms NFC acts as an additional technology, and not as the main form of communication between the cell phone, the software and the payment machine.
The NFC also serves as a method for consulting and recharging transport tickets, depending on compatibility, such as the Single Ticket from the So Paulo State Government.
