RFID Tags and Wristbands
RFID tags encode data about the items they reference. Using inductive coupling, they can be read from close range by an RFID reader.
LF tags have slower read rates and shorter ranges than UHF and HF but are less sensitive to interference from metal or liquids. They are commonly used in pet tagging and livestock identification.
High Frequency
Radio Frequency Identification works through a microchip that stores and transmits data. This microchip can be powered by batteries or a power source that is supplied by the RFID reader. There are different frequencies for the data transmission, with each frequency supporting its own set of standards.
Low frequency, or LF, RFID tags are passive and do not contain a transmitter and battery. They use near-field inductive coupling to receive power and communicate with the interrogator. This technology typically operates at 125 kilohertz or 134.2 kilohertz and has been in use since 1979 for animal tracking systems.
HF RFID tags work well with metal objects and items with medium to high water content. This technology is used in a wide variety of applications including ticketing, payments and library books. HF RFID also has anti-collision capabilities, allowing multiple tags to be read at the same time. However, water can interfere with the signal and reduce the read range. This is why it is important to test the performance of a given tag in your environment before deploying it for inventory-tracking applications.
LF
LF RFID tags have a low working frequency of 120 to 134 kHz and operate worldwide without any licensing impediments. They work well with metals and liquids and are more resistant to interference than HF and UHF.
These tags are a great choice for items that need to be in close proximity with the reader, such as a bottle of water or fruit. LF tags can also be RFID Keyfob used for animal tracking and are less sensitive to environmental factors like dirt or chemicals.
These tags can be read as far as a pinky finger away from the RFID reader but have a shorter range than HF and UHF tags. They are a good choice for applications where a small footprint is required and excel when mounted in or on metal. Specialty LF 125 KHz tags include Glass Ampoule RFID Tags, Plastic Wedge RFID Tags and RFID Nail Tags which are a great solution for tagging tress and wood assets. They are also a good choice for laundry applications as they are waterproof and resistant to chemicals.
HF RFID Key Fobs
A key fob contains a small RFID chip and transmitter to communicate with the reader. When you press a button on the fob, it transmits a distinct code to the reader device that matches with the information in its memory. This communication takes place instantaneously.
LF systems operate within the 30 KHz to 300 KHz range and are common for animal tracking and access control. They have a short read range and slow data transmission rate but are more resistant to metals and liquids than other technologies. LF RFID Tag They also provide good performance in moist environments where the higher frequencies of UHF struggle.
HF RFID tags can be made into a variety of shapes and sizes including cards, key fobs, wrist bands, coins, rings, and stickers. Because they often use the same plastic case, it can be difficult to discern the frequency they operate on from their exterior appearance. Some of these devices are easily copied by black hat hackers and can grant the same privileges as the original. This is why it is important to choose a durable, secure RFID tag for your business.
ISO Cards
With LF RFID systems, the tag is powered and communicates with the reader by reflecting the radio signal sent by the reader antenna. This is called “tag backscatter.” Because the read range is short, LF RFID systems are typically used in access control and livestock tracking applications where the tag can be affixed to a metal surface or liquid-resistant. Common standards for LF RFID systems are ISO 14223 and ISO/IEC 18000-2.
The idChamp NF4 Reader-Writer and the idChamp RS3 Reader-Writer feature dual antennas that allow users to read both LF and UHF RFID tags simultaneously. The ISO Card is made from a composite PETF/PVC material and features a printed front and rear to allow for easy identification. The card has a locked EPC field to prevent card duplication.
ISO Cards are compatible with RAIN and work with the entire portfolio of idChamp readers. These cards are a great alternative to magstripe and are much safer from hacking. They can be encoded with unique information to ensure each card is identified as the authentic credential it is.
Wrist Bands
A wristband is a great way to promote a cause or an event. It can also be used for cashless payments and access control. Wristbands work with RFID event software to provide a seamless on-site experience. They can also be personalized with unique identifiers to prevent counterfeiting.
Whether you’re organizing an event or looking to raise awareness for a particular issue, RFID wristbands are a great choice. They’re comfortable and stylish, and can be customized with your logo or message. They can be molded to fit any wrist size, and are available in a wide variety of colors.
For example, Harpoon Brewery uses the color blue for their events to show support for hurricane victims and anti-bullying campaigns. Their wristbands are a popular way to build community and attract new attendees. They also help people feel a sense of ownership over the event and encourage them to come back in the future. Wristbands also make a great giveaway item at a fundraiser or community event. They’re affordable, and many people will proudly display their bracelets for years to come.
