NFC is a versatile technology that uses RFID (radio-frequency identification) techniques to wirelessly transmit data. It is a short-range (10 cm) wireless communication technology that lets two devices exchange small amounts of data when nearby.
The technology is used in several sectors, including retail, healthcare, transportation, and marketing. But what advantages does it bring to these industries?
In this article, we evaluate the advantages of NFC in several key sectors. By the end, you will understand the benefits of this technology and realize its enormous potential for transforming everyday interactions.
How NFC Works
If you’ve ever used a contactless payment card or tap-to-pair mobile device, you’ve already interacted with NFC technology. NFC communication works by sending small amounts of data through radio waves.
It uses a short-range electromagnetic field that can be read by devices within a few centimeters (usually 10 cm). This means that it is not just limited to mobile devices, but also includes tags and cards embedded with NFC chips.
The technology is already widely used in the retail sector for contactless payment transactions, but it offers many other uses. Here’s a breakdown of some of the uses of NFC technology:
- Card Emulation NFC. This feature allows users to store credit card information directly on their smartphones. This makes it possible to pay with your phone at retail stores, restaurants, and other locations that accept contactless payments.

For these functions and many others, NFC is proving to be a transformative technology in a range of industries. With its near-instant connection capability and ease of use, it is no wonder that it has become one of the most popular technologies today.
What are the Components of the NFC System?
A functional NFC system must have several key components to work efficiently. These include:
- NFC Tags. NFC Tags are small chips or stickers embedded with an NFC radio that can transmit data over short distances. They come in a range of form factors and can be created using a variety of materials, including paper, cardstock, and plastic.
- NFC Readers. These are devices such as smartphones and point-of-sale terminals that can read and write NFC tags. They can be integrated into a range of devices, such as smartphones, smartwatches, tablets, point-of-sale terminals, computers, and vending machines.
- NFC Software Development Kits (SDKs). These are a set of tools that allow developers to program applications that use NFC technology. They typically come in the form of APIs, libraries, and documentation that can be integrated into existing software.
NFC tags are small, electronic tags that utilize Near Field Communication (NFC) technology to exchange data between two devices (approximately 4 inches apart). They can be made into different shapes & forms, ranging from stickers to key chains or even credit cards. With the rise of NFC-enabled mobile devices, these tags have become both easier and increasingly popular for several applications. So, how do they work?
At the most basic level, NFC works through radio waves, the same as radio-frequency identification (RFID). When an NFC tag is placed close enough to the receiving device (such as a smartphone or reader), it sends out a signal. This causes the receiver to establish a connection with the tag to transmit data back & forth. This entire process usually takes just seconds and requires no manual input from the user.
What sets NFC tags apart is that they can be programmed with different data types, depending on their intended use. For instance, you might program an NFC tag with your contact details before sticking it onto your business card so that anyone who scans it with their phone will automatically receive your information without having to manually type it out. Similarly, you could also program an NFC tag on your door handle to open your front door when scanned by your smartphone or a special key card that’s been programmed for guests staying at hotels or apartments.
The main types of NFC chips available on Shop NFC are:
- NTAG Series ICs. These chips are compatible with every NFC mobile device but offer limited functionality since they can only store basic information like contact details or URLs which can then be scanned by other devices for quick access.
- MIFARE Classic, MIFARE Ultralight, MIFARE DESFire, and MIFARE Plus Chips. Slightly more expensive than memory chips but offer much greater capacity and features such as locking mechanisms that allow users to lock down certain data stored within them while still allowing other functions like opening doors or transferring money.
- ST25TA and ICODE Series Chips. The most advanced type of NFC tags available offer users the ability to store multiple types of data (credit card numbers, passwords). They also feature various security measures such as dual authentication systems or biometric scanners to prevent unauthorized access.
Uses of NFC Technology
