RFID Keyfob
A key fob is a physical security token that uses RFID technology to unlock doors, monitor staff attendance and more. Key fobs are programmable and can be remotely deactivated if they’re misplaced or stolen.
They are also commonly used as a factor of authentication in 2FA and MFA systems.
RFID Technology
RFID is an electromagnetic technology that uses radio waves to identify and track objects. It is commonly used in key fobs to give people access to a building, car, computer systems or other types of physical items.
This technology is also useful in tracking inventory and products. It can quickly read multiple tags simultaneously, which helps businesses reduce operational times and improve productivity. It can even prevent errors during order fulfillment and enhance customer experiences.
In the healthcare industry, it can be used to track equipment and patients. However, some staff may have concerns about the privacy and security of Paper Card the technology. Okoniewska et al, (2012) found that while the benefits of an RFID system were numerous, there was a lack of buy-in and acceptance amongst healthcare providers.
Generally, RFID systems have a fixed cost to get started. This includes hardware like readers and antennas. These can be installed on walls, desks or into portals. The number of antennas depends on the coverage and capacity needed to accommodate a specific application.
Passive High Frequency Key Fob Tag
Key fobs are small hardware tokens that offer one-factor authentication solutions. They are used in many devices and systems that require security, from cars to computer systems. They are also often used in apartment complexes to protect residents and their belongings. Fobs can be programmed to allow access for different types of people, such as staff and contractors. This allows managers to monitor who enters and leaves the building, as well as the specific rooms that people are going into.
There are two main types of RFID tags: passive and active. Active tags have their own power sources, usually batteries. Passive tags, on the other hand, have no battery and rely on electromagnetism to communicate with a reader. When a passive tag comes within range of a reader, the electromagnetic energy from the reader’s antenna triggers the IC on the card to turn on and transmit an information-carrying signal back to the reader.
Because passive tags rely on electromagnetic energy to function, they are susceptible to interference from other electronic devices. To counteract this, manufacturers of passive RFID products have developed ways to design and engineer tags, readers, and antennas that are less sensitive to interference. Some people use Faraday cages to store their RFID key fobs, which work by blocking any unwanted signals. This is a great way to prevent your keys from being cloned by thieves.
Active High Frequency Key Fob Tag
Key fobs use RFID technology to provide one-factor authentication solutions RFID Keyfob for accessing a device, restricted area or even an entire system. They also offer greater security than traditional metal keys, and can be deactivated remotely if they are lost or stolen.
A key fob uses a short-range radio frequency transmitter and an antenna to send coded signals. These signals power a mini computer inside the fob that communicates with a reader via the same antenna. The key fob receives a signal from the reader that then transmits a unique number to the receiver, which serves as the identification credential.
These devices are especially useful in situations where a building or car needs to be secured electronically, such as with a door lock or a gate opener. They’re also used for a wide variety of other applications, including e-payment systems, livestock monitoring and more.
In addition to RFID tags, manufacturers may include a biometric authentication feature in their fobs. This feature can include facial recognition, fingerprint scanning or iris scanning and uses them to verify a person’s identity.
The type of RFID tag used in a key fob can be either active or passive, and it can have a range of different frequencies. A passive card will need to be close to a reader in order for it to work, while an active RFID tag will have its own battery that powers it and can transmit signals at a distance.
Passive Low Frequency Key Fob Tag
A key fob is a small gadget that can open your car doors or secure your home or office. Modern keyfobs work through RFID, an intelligent barcode system that uses electromagnetic fields to identify and track data on “tags” that are attached to objects or items. Each tag contains a microchip that holds information, and the chip and antenna communicate with a reader unit to exchange coded signals over radio waves.
The most common RFID tags are passive, which means they don’t have a power source. These tags receive energy from an RFID reader that passes through the antenna and enables the integrated circuit, or IC, to turn on and modulate the energy with information. The IC then transmits the encoded signal through the antenna, which allows the tagged object to be identified in close range by an RFID scanner or interrogator.
Low frequency (LF) RFID is a general-purpose technology, which can be used in various applications. These include animal identification, asset tracking, access control and e-payment systems. They are also widely used in the automotive industry as vehicle immobilizers, and they can withstand harsh environmental conditions such as vibrations.
We offer a variety of different LF RFID keyfobs, which come in various shapes and sizes. We can provide you with a wide range of customization options including silkscreen printing, numbering with inkjet and laser and packaging. We can also produce custom designed RFID key fobs for specific customer requirements.
