It enables various functionalities such as making secure transactions, exchanging digital content, and connecting electronic devices with a touch. One of the most common uses of NFC on a smartphone is for making easy and secure contactless payments, such as through services like Samsung Pay, Apple Pay, or Google Pay
. To use NFC on a cell phone, you can typically enable it through the device's settings, usually under the "Connections" or "NFC and contactless payments" section
