NFC stands for Near Field Communication, NFC is a short-range wireless technology that enables communication between electronic devices within a distance of 2cm or less. With NFC, devices can share small amounts of data by simply bringing them close together. This technology is commonly found in smartphones, tablets, wearables, and payment cards.

NFC access control operates at a frequency of 13.56 MHz with a typical range of up to 2cm and data rate from 46kbit/s up to 1.7Mbp/s and offers low-speed connections for various applications, including contactless transactions, data exchange, and simplified device setup. NFC is based on existing RFID standards and is governed by the NFC Forum, which sets standards for device compliance.

NFC access control support four main modes of operation:

  • Reader/writer mode allows the device to read and write NFC tags.
  • P2P mode enables data exchange between NFC peers.
  • Card emulation mode allows the device to act as an NFC card.
  • Wireless charging mode charges the phone by just putting it on the charger.

What are the capabilities of NFC Access Control?

NFC (Near Field Communication) technology has a wide range of use cases across various industries.

Here are some popular use cases of NFC access control:

Contactless Payments

NFC access control enables secure and convenient mobile payments by allowing users to tap their smartphones or contactless cards on payment terminals. This technology is widely used in mobile payment apps and contactless payment cards.

Access Control and Security

NFC tags can be used for access control systems in offices, hotels, and other facilities. Employees or guests can use NFC-enabled devices to gain access to restricted areas. NFC also enables secure identification and authentication processes.

Public Transportation

NFC access control is used in contactless ticketing systems for public transportation. Commuters can use NFC-enabled smart cards or smartphones to pay for fares and access public transport services. This technology simplifies the ticketing process and enhances the overall user experience.

Smart Home Automation

NFC tags are being used to automate various tasks in smart homes. By tapping an NFC-enabled device on a tag, users can control lights, adjust temperature settings, play music, and perform other actions. This simplifies the management of smart home devices and enhances convenience.

Marketing and Advertising

NFC tags are also embedded in promotional materials such as posters, flyers, and product packaging. Users can tap their NFC-enabled devices on these tags to access additional information, discounts, or promotional offers. This technology enhances customer engagement and provides interactive marketing experiences.

Healthcare and Pharmaceuticals

NFC tags can be used in healthcare settings to track and manage patient information, medication adherence, and inventory management. NFC-enabled devices can read tags on medication packaging to ensure authenticity and provide dosage instructions.

Event Management

NFC tags are used in event management to streamline ticketing, access control, and attendee engagement. Attendees can use NFC-enabled devices to enter events, make purchases, and interact with exhibitors or speakers. This technology improves event efficiency and enhances attendee experiences.

How does NFC Access Control security Work?

NFC-based access control systems consist of several components that work together to ensure secure access to protected areas.

NFC Tag Reader

The access control system is equipped with an NFC tag reader installed at the entrance or access point. The tag reader emits an electromagnetic field that powers the nearby NFC tags and establishes communication with them.

NFC Tags or Cards

Authorised individuals are provided with NFC tags or cards that contain their unique access credentials. These tags are embedded with a small chip that stores the necessary information.

Authentication Process

When an authorised individual wishes to gain access to a secured area, they present their NFC tag or card to the NFC reader. The reader then initiates communication with the tag and verifies the access credentials stored within.

Access Granting

If the access credentials on the NFC tag match the ones stored in the system, the NFC reader grants access by unlocking the door, gate, or turnstile. The individual can simply walk through the secured area

Access Denial

If the access credentials are invalid or not recognized, the NFC reader denies access and prevents entry. This ensures that only authorised individuals can gain access to the protected space.

Advantages of using NFC Access Control Systems

NFC-based access control systems offer several advantages over traditional access control methods.

Here are some key benefits:


NFC technology enables quick and contactless access, eliminating the need for physical keys or access cards. Users can simply tap their NFC-enabled device on the reader to gain entry, providing a seamless and hassle-free experience.

Enhanced Security:

NFC-based access control systems offer a high level of security. The use of unique access credentials stored on NFC tags or cards makes it difficult for unauthorised individuals to gain access to secured areas.

Easy Management:

These systems can be easily managed and administered. Access credentials can be added or revoked remotely, reducing the need for physical reissuance of keys or access cards.


NFC-based access control systems can easily scale to accommodate a growing number of users or access points. Additional NFC tags or cards can be issued, and more NFC readers can be deployed as needed.
