How the NFC works
Actually, NFC is not a new technology. Basically, NFC becomes an advanced version of RFID technology, or radio frequency identification, which is quite old. In fact, if you are familiar with the use of cards to open hotel doors or to enter a building, then you know what the NFC is about.
Both the operation of the NFC and the RFID is possible thanks to the principle of inductive coupling. When you bring your device with NFC label to a reader device, this will generate a magnetic field that will be responsible for carrying out the pairing without cables. Once the wireless contact is completed, data transfer begins immediately.
One of its main advantages is the speed of pairing, which is quite useful to use with devices compatible with this technology and that, for example, do not have screen. Just bring them closer and ready.
Thanks to the NFC, you can make contactless payments through services such as Google Pay and Apple Pay, as with many credit and debit cards. You can also pay in public transport services from the world's main capitals with just bringing the mobile closer to a reader.
It is also compatible with platforms to control devices in intelligent homes, such as Apple Home Assistant and Homekit, and can even be used in video game consoles such as Nintendo Switch. For example, there are action figures that incorporate NFC chips. As you bring this toy to your console, you receive accessories for games, collectible items, etc.
