What is the Importance of Key Fobs?

Are you looking for a simple and efficient way of managing who should be admitted into restricted areas in your business premises or who can use certain machines or devices? Then look no further than key fobs.

 

Essentially a programmable hardware token, a key fob can provide single-factor authentication for any physical object, device, room, or service. This not only enables remote-enabled access but is also more convenient and secure than traditional manual locks.

 

Key fobsare classified as physical security tokens (along with smart cards, proximity cards, and biometric keyless entry systems). They can help protect your property with an added layer of safety by granting access only to authorized personnel and devices that possess the correct credentials.

 

How dokey fobswork?

 

A key fob has a radio transmitter/RFID chip with an antenna, which transmits distinctly coded signals to the receiver device that holds an RFID tag. This communication is virtually instantaneous; when the user presses the button on their fob, it adjusts to precisely match the frequency of its transmitter for effortless activation and utilization.

 

The RFID chip embedded in the key fob is programmed to transmit a unique frequency. This code precisely corresponds with what the receiver device has been programmed to recognize and accept. For instance, a key fob programmed to lock and unlock a car will only work with that particular car. Thus, if the details from the receiver tag match with what is requested by the fob, then the locking/unlocking action is completed. If there are discrepancies between them, nothing happens.

 

Key fobs also provide a reliable and secure method of verifying an individual's identity for devices needing two-factor or multifactor authentication (MFA). These authentication strategies bolster a company's security, ensuring networks, applications, devices, and data remain protected.

 

MFA verifies a user's identity by utilizing three distinct methods: possession (something you have), inherence (something you are), and knowledge (something you know). This ensures greater protection than what is offered through standard password-only systems.

 

How can businesses benefit fromkey fobs?

Enterprises can take advantage of the extra layer of security provided by a hardware key fob, as passwords are too easy to intercept and steal. Attackers commonly employ brute-force attacks, phishing strategies, or social engineering tactics in order to access confidential information, install malware, steal data, and engage in other cybercrimes.

 

By using a key fob, you can safeguard against such attacks. A hacker would not only need the credentials to gain access to your system but also have physical possession of the key fob. Although it is possible for dedicated hackers to copy and hack these devices, if supplied with due care and vigilance, they are highly unlikely to be stolen or used maliciously in any manner.

 

Furthermore, the passcodes created by fobs are randomly generated with a unique access/unlock sequence each time and expire after a specific period. This makes it impossible for attackers to reuse any intercepted codes, even if they manage to steal them.
