What is NFC and what can I use it for?
What is NFC?
NFC stands for Near Field Communication. The maximum range to exchange data is limited to 10 centimeters. Compared to Bluetooth, less data is lost, because NFC connections won't quickly interfere with each other. On top of that, less time and energy are needed to establish a connection. With NFC, you can encode sensitive information, so you can send them without worries. Did someone steal your phone? Thanks to the NFC chip, it can be tracked down via GPS.
There are plenty of possibilities, but NFC is far from integrated in society. You can count on it as a versatile and safe way of data transfer, though. An important detail: your smartphone needs to support NFC.
