Do you have a smartphone? You will no longer be able to do without this technology

All those who have a smartphone can no longer do without a technology that is depopulating: this is what it is about.

Since the first mobile phones came into the world, people’s lives have completely changed. This is because mobile phones have evolved to become real smartphones that can do everything. It is difficult to find a person without this object, especially with the arrival of a truly revolutionary technology.

Most of today’s smartphones are equipped with a new technology that can do several very useful services for users. But what is it about? Let’s talk about Near Field Communication, better known as technology NFC. Simply put, it is a proximity-based wireless communication standard.

Unlike Wi-Fi or Bluetooth, however, NFC interaction in smartphones, which they can sometimes have battery problems due to four errorsis limited to one very short range. In addition to mobile phones, this technology can sometimes be found on tablets, speakers, collectibles, and even game consoles like Nintendo Switch and 3DS.

NFC technology in smartphones becomes a payment card

But what can it do? This technology can allow you to “talk” to a printer to initiate printing. Most importantly, NFC allows smartphones and other devices to do digital payments on the move through the POS. In short, technology turns mobile phones into real credit or prepaid cards.

There are several services where you can turn your smartphone or other device into a payment card. However, as pointed out in the Corriere della Sera, it is advisable to use Google Pay for Android devices, or Apple Pay for iOS.

How does NFC work? It is not a radically new technology. It is simply an evolution of RFID (radio frequency identification) technology that has been around for decades. NFC has a maximum range of a few centimeters, at most. And in most smartphone-related applications, software initiates communication only if there is physical contact. This is to prevent accidental activations.

Another noteworthy point is that NFC devices can act as both a reader and a tag. This bidirectional functionality lets you use a single piece of hardware, like your smartphone, for all kinds of different applications.

What devices have NFC?

NFC has been a key feature on smartphones, who often worry about radiation, for several years at this point. The Nexus S it was the first Android device to include it back in 2010. Also Apple finally adopted the technology in 2014: NFC is present on all iPhones since 6, as well as iPad and Apple Watch.
