What is NFC technology?

Introduction to NFC technology

NFC is an abbreviation for near-field communication, which is a modern technology that allows devices to communicate with each other over a short distance, usually a few centimeters. It allows you to touch your phone to a payment terminal to buy a coffee or share photos with a friend by bringing your phones closer to each other. This technology is becoming increasingly common daily due to its simplicity and effectiveness.

Basic principles of NFC

NFC technology creates a short-range wireless connection between devices, allowing seamless data exchange. It covers three types of devices:

  • Passive devices that only transmit data.
  • Active devices that only receive data,
  • Dual-function devices that can send and receive data.

This flexibility enables various applications, increasing user convenience and efficiency in digital transactions and information exchange.

Applications of NFC technology

Low-frequency NFC technology has a wide range of applications that extend beyond mobile payments and impact sectors as diverse as healthcare, transportation, and retail:

  • Mobile payments: NFC has revolutionized transacting through services like Apple Pay, Google Wallet, and Samsung Pay. They simplified payments with just one touch of the smartphone;
  • Smart ticketing: From airlines to public transport, NFC enables the use of digital tickets, simplifying access and reducing the need for physical tickets;
  • Healthcare: In the medical field, NFC can improve patient care through more accurate prescription management, simplified registration, and easy access to patient records.
  • Keyless Access: The technology enables secure and convenient access control to buildings, vehicles, and other secure areas, often replacing traditional keys and access cards;
  • Retail and Inventory Management: Assists in effective inventory management in retail stores and supermarkets by offering real-time updates on stock levels and enabling theft control measures;
  • Access to information: Like QR codes, NFC tags can instantly provide information about products or services when touched with an NFC-enabled device.

What are the advantages?

Its convenience, security, and speed distinguish low-frequency technology:

  • Ease of use: NFC’s tap-to feature makes it extremely user-friendly without requiring complex settings or configurations;
  • Security: Transactions using the technology are extremely secure, with data exchange protected by encryption and specific elements, making it a reliable tool for sensitive applications such as payments and access control;
  • Speed: NFC establishes connections and transfers data quickly, improving the user experience by reducing waiting times for authentication or data exchange.

Which devices support NFC?

The integration of technology covers a wide range of devices, improving their functionality and connectivity:

  • Smartphones and tablets: Many modern mobile devices are equipped with NFC, which enables various applications;
  • Wearables: Devices such as smartwatches and fitness bands use NFC for contactless payments and data exchange;
  • Smart Cards and Tags: Widely used in public transportation, access control, and retail systems, NFC tags and cards facilitate a seamless, contactless user experience.


The flexibility of the technology and its easy integration into various devices has paved the way for innovative applications, significantly impacting how we interact with the environment in our daily lives. From creating smart homes by controlling household appliances using NFC to enhancing the IoT sector with smarter, interconnected devices, NFC continues to open new avenues for technological advancement.
