Low Frequency (LF) Passive RFID Tags. Read distance of 30 cm (1 foot) or less – usually 10 cm (4 inches) unless you are using a very large tag which can have a read distance of up to 2 meters when attached to metal.
How is a passive RFID tag powered?
Passive RFID systems use tags with no internal power source and instead are powered by the electromagnetic energy transmitted from an RFID reader. Passive RFID tags are used for applications such as access control, file tracking, race timing, supply chain management, smart labels, and more.
How far can RFID be detected?
Passive low-frequency (LF) and high-frequency (HF) tags can be read from a distance of up to 3 feet (0.9 meter), while passive ultrahigh-frequency (UHF) RFID transponders can typically be read from 10 to 20 feet (3 to 6 meters) away.
What is low frequency RFID?
The Low Frequency (LF) band is the frequency range from 30 KHz to 300 KHz. RFID systems that operate in this frequency band are called Low Frequency (LF) RFID Systems. Low Frequency RFID tags have a long wavelength and can penetrate thin metal surfaces (HF and UHF tags can usually not be used with metallic substances).
What is RFID frequency range?
RFID TAG CHARACTERISTICS OVERVIEW BASED ON FREQUENCY
| Frequency Bands | Antenna | Read Range |
|---|---|---|
| Very High Frequency (VHF) 433 Mhz – Active Tags | Internal Custom Design | High 1-1000 feet |
| Ultra High Frequency (UHF) 860 MHz – 960 MHz | Single or Double Dipole | Medium 1-30 feet |
| Microwave Frequency 2.45 GHz & 5.4 GHz | Single Dipole | High 1-300 feet |
In which RFID tag the range is less active or passive?
Far-range UHF RFID tags can read at ranges as far as 12 meters with a passive RFID tag, whereas active tags can achieve ranges of 100 meters or more. The operating frequency of UHF RFID tags ranges from 300 MHz to 3 GHz, and UHF tags are the most vulnerable to interference.
This is an absolutely key part of the technology; RFID tags do not need to contain batteries, and can therefore remain usable for very long periods of time (maybe decades). Active RFID tags have their own power source; the advantage of these tags is that the reader can be much farther away and still get the signal.
Typically LF RFID systems operate at 125 KHz, although there are some that operate at 134 KHz. This frequency band provides a short read range of 10 cm, and has slower read speed than the higher frequencies, but is not very sensitive to radio wave interference.
What is RFID (Radio Frequency Identification)?
Radio frequency identification (RFID) is a generic term that is used to describe a system that transmits the identity (in the form of a unique serial number) of an object or person wirelessly, using radio waves. It’s grouped under the broad category of automatic identification technologies.
RFID tags support a larger set of unique IDs than bar codes and can incorporate additional data such as manufacturer, product type, and even measure environmental factors such as temperature. Furthermore, RFID systems can discern many different tags located in the same general area without human assistance.
What is the transmit frequency of the Ti low-frequency RF products?
finally to a good layout. The transmit frequency of the TI low-frequencyRF products is 134.2 kHz. The communication range for passive devices (powered by the magnetic field of a RFID reader) is typically up to 10 cm.
