The puzzle behind N, what is it and how it works?

If we see at any time the Nic symbol at the top of the cell phone, this means that the option is activated NFC ((Near the field communication) S. The near field communication.

This is it Short -term wireless technology This allows Information exchange between Two device are very closeCentimeters. It is very similar to Bluetooth or infrared, although it works differently and has other purposes.

For example, to work, NFC uses electromagnetic radiation frequency fields and the device that will be transferred to the data must be No more than four centimeters From the recipient.

In addition, although it is a slower connection, It does not require manual matchingBut the connection was created almost immediately when two devices approach with NFC.

What can be done with NFC?

About possible Power wearingNFC battery consumption is very little, and it is only activated when used for a long time. Therefore, there is no problem in leaving it, because this does not mean that it is used all the time.
