Many smartphones have integrated the new NFC technology. It not only allows you to share audio files, videos, contacts, but also to pay for your trips in urban transport.

NFC on Android: what is it exactly?
The functionality of this new transmission technology wireless is short range. It allows compatible devices or two smartphones to exchange their information. The overall idea of this feature is to share data or launch a connection with a reduced level of security, but for a limited time.
That is to say, unlike the Bluetooth system and wifi, it is quite possible to connect within a few meters. On the other hand, the NFC must be done within a distance of a few centimeters. In some cases, it is often required to position the transmitter and the receiver correctly so that the transfer is done properly.
Without any effort on your part, NFC simplifies pairing app data, photos, videos, files and more with other devices by simply bringing the two smartphones close together. Note that the first smartphone to use this feature is the Samsung Galaxy Nexus from 2011. Subsequently, several other smartphones have adopted this transmission system.
To find out if your smartphone has this feature, all you have to do is go directly to the settings and click on More from the wireless wifi menu.
In this case, either you see the NFC title and click on it to activate it, or not (your smartphone is not equipped).
Enabling and disabling NFC on Samsung: how to proceed?
This new wireless communication technology allows you as a user to transfer andexchange information with other smartphones.
So, to activate and deactivate it, you should know that it is available in Android 9, 10, 11 and 12. To do this, here are the steps to follow:
- by swiping from the bottom to the top, you can access the applications;
- you can see the settings icon and click on it;
- click on where it says connection “wifi, bluetooth, offline mode”;
- activating or deactivating NFC is done using the slider by sliding it to the right.
Using the NFC Tag: how does it work?
Apart from payments in public transport as well as data sharing, it is quite possible to deactivate and activate a specific application from another device or a smartphone. Using NFC, in case you get into your car and want the wifi to turn off automatically without you doing the maneuver, it’s easily done.
For it, use the NFC tag which is located in your passenger compartment. Then rub the back of your smartphone over the NFC tag and your wifi will be disabled.
It is also possible to activate or deactivate other features such as Bluetooth or airplane mode.
In addition, be aware that NFC tags can also appear on business cards, medicines, cinema tickets, etc. Although this is quite rare, but anything is possible with this wireless communication technology.
The bottom line is that NFC allows you to save time while limiting expenses and data transfer.
Therefore, note that cell phones are not immune to theft. For this, it is important to protect your device by locking and erasing your data remotely.
