How does NFC work

When we activate NFC by going to the settings of our mobile, it creates an electromagnetic circle in the area around us through the electromagnetic radio field. Similarly, you can activate NFC in the other device as well, when the electromagnetic field of these two touches each other, then a connection will be made between the two. Now you can share data between both the devices, when data is sent from one device to the center mode, then the other device will have to turn on the receive mode, so that the data can reach. The same process will have to be followed to send the data to the other device. This is how this connection works.
