What is an NFC keyfob?

An NFC keyfob is a small device that contains an NFC chip and antenna. The chip is capable of storing and transmitting data when it comes into close proximity with an NFC-enabled device. These keyfobs are commonly used for access control systems, identification, and authentication purposes. More information can be found on this handy article from Webopedia which outlines what an NFC fob is.

NFC keyfobs are similar to RFID (Radio Frequency Identification) keyfobs, but with a few key differences. While both use radio waves to communicate with other devices, NFC has a shorter range of communication and can only work within a few centimeters. This makes it a more secure option for access control systems, as it ensures that only those with authorized access are able to gain entry.

How do NFC keyfobs work?

NFC keyfobs work by utilizing the NFC protocol, which is a set of communication standards for wireless devices. When an NFC keyfob comes into close proximity with an NFC-enabled device, the two devices establish a connection and exchange data. Very commonly the fob is connected to a custom printed lanyard and that is worn by the user on a daily basis. They simply raise the fob to the door panel system to gain entry to the door or building.

To use an NFC keyfob for access control, the keyfob is first programmed with the user’s access credentials. When the user approaches the access control reader, they simply hold the keyfob up to the reader, and the reader reads the credentials stored on the keyfob. If the credentials are authorized, the reader will grant access to the user.

In addition to access control, near field communication keyfobs can also be used for identification and authentication purposes. For example, a company may issue NFC door fobs to its employees to use as identification badges. The keyfob could contain the employee’s name, photo, and other identifying information, making it easy to verify their identity when they enter the workplace.

What are the benefits of using NFC keyfobs?

NFC keyfobs offer a number of benefits for access control and identification purposes. Some of these benefits include:

  1. Convenience: NFC keyfobs are small and easy to carry around, making them a convenient option for users who need to access multiple areas throughout the day.
  2. Security: Because NFC keyfobs can only communicate with NFC-enabled devices in close proximity, they provide an extra layer of security for access control systems. This makes them a popular choice for secure environments such as hospitals, government buildings, and data centers.
  3. Versatility: NFC doorfobs can be programmed to store a wide variety of data, including access credentials, identification information, and payment information. This makes them a versatile option for a variety of use cases.
  4. Durability: NFC keyfobs are typically made from durable materials such as plastic or metal, which means they can withstand daily wear and tear without becoming damaged or unusable.

What are the limitations of using NFC keyfobs?

While NFC keycards offer a number of benefits, there are also some limitations to consider. These include:

  1. Range: NFC has a very short range of communication, typically only a few centimeters. This means that users need to be very close to an NFC-enabled device in order for the keyfob to work.
  2. Compatibility: Not all devices are NFC-enabled, which means that NFC keyfobs may not be compatible with all access control systems or identification systems.
  3. Cost: While NFC keyfobs are relatively inexpensive to manufacture, the cost of implementing an NFC-based access control system can be high. This is because it typically requires the installation of a door entry system that is compatible with the fobs. That being said, many offices or large buildings are installing this type of system as standard which allows for access 24 hours a day.
