RFID key fob is a small, lightweight device that attaches to a key ring and contains an RFID tag. It is commonly used for access control, where it is scanned to unlock doors or gates.
The key fob consists of a chip and an antenna. The chip contains the unique identification number of the RFID tag, while the antenna emits radio frequency signals to activate the tag.
When a reader detects this signal, it will capture the tag’s ID and relay it to a computer or control system. The key fobs are made out of different materials, including:
The choice you make depends on your needs. For example, Epoxy key fobs are hardy. They can withstand chemicals and high temperatures.
Key fobs are used for several applications, including access control, vehicle identification, and inventory tracking. Here’s a detailed analysis of these applications:
This is the most common use for RFID key fobs. It is embedded with an RFID chip containing a unique ID number.
When the fob is scanned, the reader captures the ID and sends it to a control system, which unlocks the door.
Additionally, companies can use RFID key fobs to segregate employees into different areas of the workplace. For example, a company might have a secure area that is only accessible to employees with a specific fob.
Such places contain sensitive information or equipment that should not be accessible to everyone. This boosts accountability and security by ensuring that only authorized personnel can enter these areas.
RFID key fobs can be used for vehicle identification. The fob can be embedded with a chip that contains the Vehicle Identification Number (VIN) of the car.
When the fob is scanned, the reader captures the VIN and sends it to a computer or control system. This information can then be used to track the car’s movements and whereabouts.
This is especially useful for stolen vehicles. If a thief attempts to steal a car, the police can use the RFID key fob to track its location.
RFID key fobs can also be used for inventory tracking. The fob can be embedded with a chip that contains the product’s code.
When scanned, the reader captures the code and sends it to an RFID software system. This information is then used to track the movement of specific products.
This is useful for high-value items, such as jewelry and pharmaceuticals. It ensures that the inventory is properly tracked and accounted for at all times.
Yes, your key fob can be reprogrammed to disable it if it is stolen. This way, the thief will not be able to gain access to your home or office.
No, an RFID key fob is not the same as a proximity card. A proximity card uses NFC technology to transmit data. On the other hand, a key fob uses RFID technology.
There are many benefits of using RFID key fobs. Some of the top benefits include:
No, RFID key fobs cannot be used to track people in the open since it is not possible to install RFID readers everywhere. They can only be used to track the movements of employees and guests within confined areas.
Some common uses for RFID key fobs include granting access to gated communities, healthcare facilities, schools, and corporate offices. They can also be used to track the movements of employees and guests.
Yes, RFID key fobs are safe. They use Radio Frequency Identification technology to transmit data. This technology is harmless and does not pose a threat to people or property.
