What is NFC?

NFC is a wireless technology based on RFID, that is often used in various cards in daily life. NFC enables short-range communication between two compatible devices, typically an NFC tag and a smartphone or tablet.

NFC tags are small chips that store data, usually integrated into stickers, magnets or tags. Most smartphones and tablets are capable of reading data from NFC tags within a short range (about four inches).

What is RFID?

RFID, which stands for Radio Frequency Identification, is a powerful technology for uniquely identifying items using radio waves. It operates through a wireless and contactless data transmission method, utilizing tags or cards to store information without the need for a continuous power source.

Comprising three essential components, an RFID system includes RFID tags, RFID readers, and a central database. When an RFID tag comes into proximity with a reader, the reader emits radio waves that activate the tag’s integrated chip. Once the chip receives the signal, it transmits stored data, such as product details or a serial number, back to the reader. Subsequently, the reader can transmit this data over a network to a central database for processing and storage.

Once the basic principles of NFC and RFID are understood, it becomes clear how these technologies differ from each other.

Operating Frequency: RFID operates across various frequencies, including low frequency (LF), high frequency (HF), and ultra-high frequency (UHF), depending on the application. For example, LF RFID (125kHz) is commonly used for access control systems, while UHF RFID (860-960MHz) is efficient for inventory management in a warehouse. On the other hand, NFC is limited to a single frequency of 13.56MHz. This frequency enables compatibility between NFC-enabled devices worldwide, ensuring seamless communication between devices from different manufacturers and brands.

Working Distance: RFID systems typically have a longer working distance compared to NFC. RFID tags can be read from several meters to tens of meters away, making them suitable for applications such as tracking items in warehouses or toll collection on highways.

In contrast, NFC has a shorter working distance, typically within 10 centimeters. This close proximity requirement ensures secure and reliable data exchange between NFC devices. For instance, contactless payment terminals require users to tap their smartphones within close range to initiate a transaction.

Communication Mode: RFID predominantly supports one-way communication, enabling the reader to retrieve data stored on the tag. This feature is commonly used in applications like inventory management or tracking items in a supply chain.

On the other hand, NFC supports two-way communication, allowing not only the reader to retrieve data from the tag, but also enabling the tag itself to receive commands or initiate actions. This bidirectional capability enhances the versatility of NFC in applications such as peer-to-peer data transfer, smart home automation, and mobile payments.

Data Reading and Writing: RFID systems are primarily designed for data reading purposes, allowing devices to retrieve information stored on RFID tags. For instance, in a library, RFID readers can quickly scan books to identify their titles or authors.

However, RFID tags generally do not support data writing, meaning the stored information cannot be altered once the tag is programmed. In contrast, NFC technology enables both data reading and writing capabilities. This allows users to interactively update and modify the information stored on NFC tags or devices. For example, NFC-enabled smartphones can write data, such as contact information or URLs, onto programmable NFC tags to share with others.

Scope of Application: RFID finds applications in a wide range of industries and sectors, including logistics, inventory management, supply chain, access control, and electronic payment. It facilitates automated tracking, authentication, and identification processes.

In comparison, NFC is primarily used for short-range data transmission and is commonly found in applications such as mobile payments (e.g., Apple Pay, Google Pay), access control systems for buildings, public transportation ticketing, and data exchange between smartphones (e.g., file sharing, contact sharing). NFC’s focus on secure and convenient short-distance communication makes it suitable for applications that require quick and easy interactions within close proximity.

Summary and Outlook

Now, we try to summarize the characteristics of NFC and RFID in short sentences.

nfc and rfid

RFID offers longer working distances while NFC works at short distances. The former has a wider scope of action, while the latter is more secure.

RFID only supports one-way communication, while NFC supports two-way communication. Therefore, RFID is mainly used to read data on tags, while NFC supports both reading and writing functions.

The RFID industry is relatively mature and well suited for large-scale adoption. NFC focuses on safe and portable short-distance interaction, suitable for data exchange.

In the future, RFID and NFC technologies may also be combined with life sciences and digital systems. Even in Sweden, some companies have tried to study the implantation of tiny NFC chips in the human body to achieve more efficient data exchange. All in all, understanding the difference between RFID and NFC can help you better choose the appropriate wireless communication technology to meet your needs.
