Radio frequency identification rfid uses electromagnetic fields to automatically identify and track tags attached to objects.
Rfid high frequency range.
However most uhf rfid systems operate between the 860 960 mhz bands.
High frequency hf passive rfid tags maximum read distance of 1 5 meters 4 foot 11 inches usually under 1 meter 3 feet and you can use a single or multi port reader plus custom antennas to extend the read range to longer tag read distances or a wider rfid read zone.
Passive rfid has a very short range but they are still very popular because they are inexpensive and they last a long time without service.
An rfid tag consists of a tiny radio transponder.
Ultra high frequency uhf is the itu designation for radio frequencies in the range between 300 megahertz mhz and 3 gigahertz ghz also known as the decimetre band as the wavelengths range from one meter to one tenth of a meter one decimeter radio waves with frequencies above the uhf band fall into the super high frequency shf or microwave frequency range.
High frequency hf rfid 13 56 mhz.
The uhf frequency band covers the range from 300 mhz to 3 ghz.
Has a range of about 30 meters.
Rain rfid is a good solution when trying to track multiple products at one time such as large boxes full of product that is passing through a space or a cabinet full of inventory.
Ultra high frequency rfid technology also known as rain has an extremely high read range compared to both lf and hf rfid tags.
When triggered by an electromagnetic interrogation pulse from a nearby rfid reader device the tag transmits digital data usually an identifying inventory number back to the reader.
Typically has a range of a few centimeters.
A radio receiver and transmitter.
High frequency tags work fairly well on objects made of metal and can work around goods with medium to high water content.
Typically hf rfid systems work in ranges of inches but they can have a maximum read range of about three feet 1 meter.
The primary exceptions are rfid systems that operate at 433 mhz and 2 45 ghz.
Ultra high freqency uhf rfid 433 mhz 900 915 mhz.
Low frequency lf rfid 125 khz 134 khz.
Ultra high frequency is referred to the frequency range 300mhz to 3ghz in the radio spectrum.
Uhf operates primarily in 860 956mhz range allowing for shorter antennas and longer read distances.
Ultra high frequency uhf rfid.
1 pet and ranch animal identification.
Rain rfid systems comply with the uhf gen2 standard and use the 860 to 960 mhz band.
Ultra high frequency uhf transponders tags inlays readers and printers.
