Modern key fobs work through RFID, an intelligent barcode system that uses radio waves to identify and track data on “tags.” They can be used to open doors by holding or waving them over a reader.

In addition to their convenience, key fobs offer more security than traditional keys. For instance, if an employee is fired, you can cancel their entry access immediately.


If you’re looking for a more secure entry system, RFID key fobs are an excellent choice. They allow you to monitor building activity and grant access based on permissions. They also eliminate the need to hand out physical keys, which are easy to misplace or copy. These fobs are ideal for hotels, apartment complexes and even office buildings.

Unlike traditional keys, RFID-enabled key fobs use short-range radio transmitters to send coded signals. They are typically composed of a microchip and an antenna that receives and transmits radio waves. They are used in a wide variety of applications, including access control, identification, and time recording.

They’re also effective for elevators, as you can regulate who has access to them based on your needs. In addition, they’re more convenient than handing out keys to visitors and delivery personnel.

They can also be used to access parking lots or public transportation. They can even be used to check-in at brand activation events, allowing users to share their experiences with friends and followers on social media.

While RFID key fobs are more secure than traditional keys, they can be hacked. To protect against these threats, you should use only reputable manufacturers. While some web shops may offer lower prices, their products are often of inferior quality. Some may stop working after a short time, or contain a chip that is not specified in the technical description. It is also important to note that RFID tags can be copied or cloned, which can lead to fraudulent activity. For this reason, you should be wary of purchasing cheap RFID products online.


Key fobs are an excellent alternative to traditional keys, providing a wide range of security and convenience features. They use RFID technology to encode digital data in a form that can be read by the receiver. This eliminates the need for mechanical keys, reducing the risk of theft and allowing you to remotely deactivate them if they are lost or stolen.

Key fob entry systems also offer greater convenience for employees in a business setting. Fobs can easily be reprogrammed to provide access to different areas and personnel, making them an ideal solution for access control in office buildings and other workspaces.

They are easy to use and eliminate the need for wiggling a metal key in a lock. Simply hold the fob or wave it near the lock to open it. They are also convenient for people with disabilities that make it difficult to turn a physical key.

They are more secure than keys, as they are encrypted and cannot be duplicated. They also prevent hackers from exploiting the passcodes transmitted on each fob. If you want to maximize the security of your key fobs, consider storing them in a Faraday pouch. These pouches are designed to protect RFID signals and can be found in a variety of sizes to fit most key fobs.


Depending on the system and features you choose, RFID Keyfobs can be expensive. However, they provide an excellent level of security that’s hard for criminals to breach, so their cost-effectiveness makes them a worthwhile investment for businesses and property owners. They are also reusable, so they reduce waste and environmental impact.

Modern key fobs work through RFID, an intelligent barcode system that uses electromagnetic fields to identify and track data on a tag. These tags are affixed to objects, such as cards and keys, or embedded in items like cars and appliances. To unlock a door, the credential needs to be presented to an access reader, which communicates with the key RFID Keyfob fob via wireless signals. If the reader receives the correct signal, it instructs the doors to open.

RFID technology can be integrated into a variety of consumables and accessories for cashless payment, access control, branding, and more. For instance, it can be added to lanyards, RFID bracelets, and season tickets so that fans, guests, and participants can pay for food, drinks, merchandise, and services without the need for cash. The chips on these items hold account balances and the purchase amount is deducted from an available balance when scanned. Moreover, they can be easily reprogrammed when a chip is lost or damaged, eliminating the need for costly replacements and administration costs.
