RFID Keyfob Technology

Key fobs make your entry systems more efficient, secure and streamlined for your staff. They work through RFID, which uses electromagnetic fields to track information on tags.

They’re easy to use for time and attendance tracking, so you can be sure employees are following their assigned work schedules. They’re also an excellent way to upgrade your security with two-factor authentication.


Unlike traditional keys that can be copied and replicated, RFID key fobs have built-in security features to prevent theft. Specifically, they use encryption methods to scramble data between the fob and the access point, making it difficult for hackers to steal information from the signal. Fobs also feature a passcode that only works for a brief period of time, which prevents hackers from using stolen fobs to gain unauthorized access.

Adding an extra layer of security, many RFID key fob systems offer biometric authentication as part of their multi-factor authentication (MFA) system. Biometrics are unique to each person, making them an excellent way to protect access and ensure that only authorized users can use the system.

The use of multiple factors increases the difficulty for bad actors to successfully breach a system, which is especially important when it comes to sensitive information or assets like inventory. To reduce the chances of data breaches, many systems also use a secure transmission protocol to communicate with the reader.

To further improve the security of RFID key fobs, some systems require a longer read range than others. Generally, the higher the frequency band of an RFID key fob, the more secure it will be. Also, inexpensive “RFID sleeves” and “Faraday bags,” which contain metal, can help shield RFID fobs from hacking attempts.


Unlike traditional keys, RFID key fobs contain encrypted codes inside their microchip. This helps prevent thieves from picking locks or making copies, and it also makes them much harder to hack into. Additionally, some RFID Keyfob RFID key fobs feature a “sleep mode” that turns off RF signals after a certain period of time. Check your manufacturer’s documentation to learn more.

Convenience: RFID key fobs can be easily attached to a badge clip or lanyard, making them easy to carry and use. They’re also a great option for people who want to boost security with two-factor authentication. In addition, RFID key fobs are small and lightweight – perfect for adding to key rings or necklaces.

For apartment complexes, RFID key fobs provide a convenient way to grant access to common areas. They can also be used to control when residents can use a particular service, such as the gym. This can help to keep buildings secure and prevent theft from tenants who aren’t authorized to use the facility.

Another way that RFID key fobs can improve security is by preventing theft of equipment or tools. By attaching specialized RFID tags to expensive assets, employees can track their location and reduce the chances of them being stolen. The tags are also a convenient alternative to traditional key fobs, which can be difficult for workers to keep track of.


Many establishments like hotels use RFID key fob to tighten their security and simplify some complex tasks. This technology makes it easier for the hotel staff to give keys to guests without running security checks, which can save a lot of time and effort. It also prevents theft, robbery and other security issues.

The RFID chip and antenna needed to communicate with the reader device are safely tucked away in the key fob. So, it’s virtually impossible to disrupt the system by attempting to copy or transfer information to a different key fob. This is an important advantage over passwords, which can be stolen or intercepted by malicious actors to steal identities, install malware, demand a ransom, or commit other cybercrimes.

Modern key fobs are incredibly reliable, even when used over long distances. In fact, one test found that a Toyota key fob wrapped in aluminum foil wasn’t able to transmit a signal to the car. This means that even if someone was to try to clone your key fob, it would be nearly impossible to do so from more than a few feet away.

These benefits of key fobs make them a great choice for business purposes, including access control systems and employee tracking. Using the right software, businesses can instantly block fobs that are lost or stolen and keep track of their employees’ arrivals and departures to generate accurate time sheets.


If your establishment uses key fobs, it is important to understand the technology behind them. This way, you can protect your business from theft. Fobs use radio frequency identification (RFID) to communicate with devices. RFID works like RFID Keyfob a barcode system, sending unique coded signals that match the specific microchip in your device.

This system allows you to control who can enter your business and when. For example, you can assign different identifiers to each employee. This allows you to track their entry and exit and evaluate employee performance. You can also use this information to prevent theft by limiting access to sensitive areas.

Another advantage of LF/HF blank RFID tag is that it’s easy to reprogram. You can change its information by touching a button on the fob. You can even create a master key fob that opens all doors, so you can get into your car or hotel room even if you lose the original.

Another potential disadvantage of key fobs is that thieves can steal their signals. This isn’t just a problem for cars, but also for passports and other forms of ID. Criminals can amplify the signal and capture your data from a distance. Fortunately, there are several ways to prevent this type of theft, such as purchasing a signal-blocking pouch. Some companies are also developing a special type of RFID fob that uses frequency-hopping technology, which makes it harder for thieves to steal your signal.
