UHF means UHF, and UHF tags are among RFID tags.
RFID is the abbreviation of Radio Frequency Identification, which is radio frequency identification technology, commonly known as electronic tags.
UHF electronic tags belong to RFID tags
RFID electronic tag package active electronic tags also known as active tags, semi-active electronic tags, passive electronic tags (passive tags)
The UHF electronic tag is a passive electronic tag. When the tag is out of the read range of the reader, the electronic tag is in a passive state. When the reader is within the reading range, the electronic tag extracts the radio frequency energy from the reader. The power needed for work. Passive electronic tags generally use reflective modulation to complete the transfer of electronic tag information to the reader.
UHF tags have features such as long distance identification, high reading rate, strong anti-collision capability, and good scalability. The UHF tags have a reading distance of 3 to 10 meters and can read 100 cards per second.
