So you have probably heard about RFID key fobs. If it is your first time hearing about it, you have come to the right place. Modern key fobs offer a simple way for businesses to manage entry into their establishment.
A key fob is a physical device that is small enough to attach to a keychain. It opens or unlocks doors electronically. It was first introduced in the market in 1983. Over the years, technological development has honed its capabilities making it better.
In the early times, RFID key fobs were used to open car doors. It uses the line of sight and infrared. However, they are highly susceptible to counterfeiting. Throughout the years, Its have developed a more secure system. This system functions through RFID tags. Unlike the older system, it uses radio frequency signals to receive data. It is difficult to copy and manipulate.
How do RFID key fobs work?
RFID key fobs have RFID tags. It uses electromagnetic fields to track data on tags. Tags are where information is usually stored. To open the door using a key fob, you simply need to hold your fob in front of the reader. Each key fob has a unique microchip that the reader will identify. If you present the correct key fob to the reader, the door will automatically open.
Establishments like hotels use key fobs to tighten door security. However, you have the option to reprogram one key fob to open all doors. They call it a master key fob. In case the customer loses his key fob, the management can still gain entry to the room.
RFID Key Fob vs. Proximity Key
A proximity key is a fob that allows keyless entry. Like a key fob, it uses RFID technology to transmit data and gain entry to the door. However, it does not need to be waved in front of the reader. A proximity key can still unlock a door even when inside your bag or pocket.
On the other hand, the RFID key fob needs to be waved in front of the reader. Proximity keys are fundamentally used for cards. However, they are slowly adopted for building access control systems.
RFID Keyfob By Frequency
RFID keyfobs can operate at various frequencies depending on the specific technology used. The three most common frequency ranges are:
- Low Frequency (LF) RFID Keyfobs: LF keyfobs provide a unique way to secure access, identify people, and track important assets. Operating at 125 kHz with an impressive read range of just a few centimeters, they are the perfect solution for any organization looking to empower safety measures while maintaining convenience.
- High Frequency (HF) RFID Keyfobs: HF keyfobs are powerful little devices that can be used for a variety of applications. With their impressive 13.56 MHz frequency and read range of up to 1 meter, they’re becoming increasingly popular in contactless payment systems, public transportation ticketing solutions, and electronic passports around the world!
- Ultra-High Frequency (UHF) RFID Keyfobs: UHF RFID Keyfob Specialties offer an unbeatable read range of several meters, enabling you to manage your supply chain and track inventory with ease. Take advantage of the 860-960MHz frequency for vehicle identification and more!
With the advent of RFID technology, it’s essential to be mindful that not all keyfobs are compatible across various frequency ranges. Depending on your application’s requirements, you must ensure each device is tailored with a specific protocol and standard – in order for optimal communication between devices!
