RFID Label UHF Tag

RFID label is a paper or plastic label with RFID inlay embedded inside, it’s normally used for warehouse management, assets sorting, logistic management, library management, anti-counterfeiting, etc.

How Do RFID Tags Work?

RFID tags communicate with RFID readers and antennas via electromagnetic waves. The reader/ antenna combination directs electromagnetic radio waves to the RFID tags in the vicinity. The energy from the waves, harnessed by the RFID tag’s antenna, forms a current moving towards the center of the tag energizing the integrated circuit (IC). The IC turns on, modulates the energy with data from its memory banks, and directs a signal back out through the tag’s antenna. The remaining, modulated energy that replies to the reader/antenna is known as “backscatter”.

What's Inside a UHF RFID Tag?

A basic UHF RFID tag is comprised of an antenna and the IC.

Antenna – A tag’s antenna is unique to that specific type of tag and its job is to receive RF waves, energize the IC, and then backscatter the modulated energy to the RFID antenna.

Integrated Circuit (IC)/Chip – the integrated circuit, also called the chip, contains four memory banks, processing information, send and receive information, and anti-collision protocols. Each IC type is unique, and there are only a handful of manufacturers. The main variation between ICs is the number of bits in the respective memory banks.

RFID label, RFID sticker contains both back glue and top coated paper or PET, the structure is Coated paper/PET+antenna + chip + chip package + glue + release paper. RFID label packaging can be divided into fold, roll and single product. Products can be divided into thermal printing and heat transfer printing; materials can be paper, waterproof materials and PVC or PET for choice, size diversity for customers to choose, encryption processing, personalized and coding services, thermal printing full package
