What Is UHF RFID Label And UHF RFID Tag

UHF RFID label

We’ve redesigned the UHF RFID label from the ground up to save you money without compromising performance. A battery-assisted passive has a small battery on board and is activated when in the presence of an RFID reader. The RFID tag receives the message and then responds with its identification and other information. Since tags have individual serial numbers, the RFID system design can discriminate among several tags that might be within the range of the RFID reader and read them simultaneously.

UHF RFID label contain at least two parts: an integrated circuit for storing and processing information, modulating and demodulating a radio-frequency signal, collecting DC power from the incident reader signal, and other specialized functions; and an antenna for receiving and transmitting the signal. The UHF RFID tag includes either fixed or programmable logic for processing the transmission and sensor data, respectively.

For example, in 2009 researchers at Bristol University successfully glued RFID micro-transponders to live ants in order to study their behavior. Hitachi holds the record for the smallest RFID chip, at 0.05mm×0.05mm. This is 1/64th the size of the previous record holder, the mu-chip. The RFID tag can be affixed to an object and used to track and manage inventory, assets, people, etc. RFID offers advantages over manual systems or use of bar codes The tag can be read if passed near a reader, even if it is covered by the object or not visible.

The tag can be read inside a case, carton, box or other container, and unlike barcodes, RFID tags can be read hundreds at a time. Sewn-in UHF RFID label in garment manufactured by the French sports supplier Decathlon Front, back, and transparency scan. RFID provides a way for organizations to identify and manage tools and equipment, without manual data entry. UHF RFID label are widely used in identification badges , replacing earlier magnetic stripe cards.

The RFID antenna in a permanently installed coupling half unmistakably identifies the RFID transponder placed in the other coupling half after completed coupling. The coupling’s location can be clearly identified by the RFID transponder coding. In many countries, CXJ RFID tags can be used to pay for mass transit fares on bus, trains, or subways, or to collect tolls on highways. Implantable RFID chips designed for animal tagging are now being used in humans. An early experiment with RFID implants was conducted by British professor of cybernetics Kevin Warwick , who implanted a chip in his arm in 1998.
