What is NFC and how does it work?

NFC (near-field communication) allows two devices placed within a few centimeters of each other to exchange data. In order for this to work, both devices must be equipped with an NFC chip. For example, using NFC, you can touch two Android devices together to transfer data like contacts, links, or photos.

How does near field communication work?

Near-field communication transmits data through electromagnetic radio fields to enable two devices to communicate with each other. To work, both devices must contain NFC chips, as transactions take place within a very short distance. With near-field communication, you must perform an action intentionally.

How does NFC store data?

Adding data to an NFC tag is called encoding. The data is usually stored in a particular way called NDEF (NFC data exchange format) encoding. This universal way of storing NFC information means that almost any NFC enabled device will be able to read and understand the data and what type of data it is.
