NFC technology has been on the market for several decades and does not differ much from other RFID technologies. The principle of operation is very similar, there is a small contactless chip with an antenna that can receive a signal from the reader, and communicate some information. 

NFC technology has gained even greater visibility and usability in recent years, as it is now being incorporated into smartphones by probably all phone manufacturers. These phones can communicate securely with POS terminals during banking transactions, they can encode NFC chips, read the NFC tags, and communicate with other NFC phones too.
NFC is proximity-based technology, which mean that it works usually just a couple of centimeters from a reader or you have to actually tap on the NFC tags. 

NFC chips can be embedded into various products to identify and authenticate them. People can use NFC transponders to unlock doors, record presence at work, etc. NFC can launch websites, open video presentations, and in recent years the technology is increasingly present in mobile payment solutions.

Since the possibilities of use are practically unlimited, we have summarized the 13 typical examples of the use of NFC technology. 

The term ‘NFC tag’ is commonly used when searching for different kind of NFC transponders like NFC stickers, key fobs, discs, cards, labels, and even wristbands. This article hopes to clarify the differences so you know which transponder best suits your needs, and you will get the appropriate NFC product. 
 

Are you designing an innovative solution and need RFID cards to identify users or make cashless payments? Have you heard about 125 kHz chips, NFC, or Mifare, and would like to know the difference? In this article, you will learn about the differences between different kinds of RF chips to help you find the best chip for your project.
