What is a "Vhf Rfid"? The Most Authoritative Explanation.
How does a UHF RFID system work?
How does a UHF RFID System Work? The RFID reader emits radio waves of specific frequencies through RFID antennas. The waves "give energy" to the tags so that they can communicate by emitting a unique ID. They do not need batteries and can be used for many years.What is high frequency (HF) RFID technology?
The high frequency (HF) band on the RF spectrum extends from 3 MHz to 30 MHz. The wavelength of a high frequency wave is much shorter than an LF wave – only around 22 meters, or a little less than 2 school buses in length. High frequency, like low frequency, uses magnetic coupling to communicate between the tags and the RFID reader/antenna.What are UHF RFID hard tags?
UHF RFID hard tags are classified as such because they are rigid and thicker than the paper-thin labels/inlays. Hard tags are made from many types of materials such as polycarbonate, ceramic, ABS, steel, polystyrene, and polypropylene. Because of the tougher exterior and larger size, these tags are more expensive than labels and inlays.What is the difference between HF RFID and NFC RFID?
HF RFID readers are used with HF tags and are relatively low in cost, generally not more than a few hundred USD. NFC tags can be read with the same HF readers, including any smartphones that contain HF/NFC readers. The ability to be read by smartphones give HF/ NFC tags the ability to gain widespread popularity in countless applications.Related Articles
