What is NFC technology and how does it work
Near Field Communication, abbreviated as NFC, has recently become a common and well-known technology that helps you instantly pay for purchases without using cash or cards, pay for travel, transfer data or open an intercom. All this is possible thanks to the built-in contactless module, which operates at a short distance (no more than 10 cm).

How to turn it off?
It’s very easy to understand how to disable contactless payments on a card. Depending on the version of Android and the shell on the smartphone, the steps may vary.

By swiping your finger down from the top of the screen, you can find the icon to turn off NFC.
How to disable NFC if the service capacity is used up? If, when completely cleaning the phone, the fullness of 120 percent or more is displayed, you will have to reset the device settings via recovery. Unfortunately, there is no other solution.
If the switch was not found, you will have to find out whether contactless payment can be disabled on the card only through the settings. If you have a search option, you just need to enter the NFC phrase and open a tab with its parameters. If your smartphone does not have such an option, you can look for the required tab in the “Connection Settings” section. Once you find the switch, deactivate it.
Disabling a module only makes sense when it is not being used in any way. Even if you use NFC infrequently, it is better to keep it turned on to make its operation comfortable and not to activate the chip again and again to make contactless payments.
