5 Things You Must Know About UHF Passive RFID Tags

UHF RFID technology is changing our life. Among RFID tags, UHF RFID Tag has its own distinct characteristics. And its applications are very extensive. For beginners, it is difficult to figure out RFID tags accurately. In this post, we will introduce UHF RFID tags in detail.

1\ What is a UHF Passive RFID Tag?

UHF RFID Tag is one of the RFID tags, often operates at 860~960 MHz, in accordance with ISO/IEC 18000-6C(63) or ISO/IEC18000-6D(64). UHF RFID tags use the far-field radiative coupling principle or backscatter coupling principle.

Unlike LF and HF, there is no unified standard in the world at present. The specific regulations of the UHF band vary from country to country all over the world.

  • European Union(EU): 865MHz~868MHz
  • Japanese: 952MHz~954MHz
  • United States: 902MHz~928MHz
  • Canada: 902MHz~928MHz
  • South America: 902MHz~928MHz
  • China: 840~844MHz or 920~924MHz
  • Hong Kong: 920MHz~925MHz
  • Singapore: 920MHz~925MHz
  • Thailand: 920MHz~925MHz

2\ What are the Advantages of UHF RFID Tags?

  • Able to identify moving objects at high speed
  • Multiple tags can be identified at the same time
  • Strong penetration and resistance to adverse environments
  • Strong security and confidentiality
  • Long-read ranges are relative to other operating frequencies
  • Reusable and large memory capacity

3\ What is Inside a UHF RFID Tag?

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

Antenna: A tag’s antenna is unique to that specific type of tag. It receives RF waves, energizes the IC, and then backscatter the modulated energy to the RFID antenna.

IC/ Chip: RFID chip is the core of tags. Each IC type is unique. The main variation between ICs is the number of bits in the respective memory banks. It contains four repositories: processing information, sending and receiving information, and anti-collision protocol.

4\ What does UHF RFID Tag Apply For?

  • Supply Chain Management
  • Production Line Automation Management
  • Air parcel Tracking
  • Container Management
  • Parking Access Control
  • Electronic Toll Collection
  • Library Management
  • Warehouse and Asset Management

5\ How to Choose UHF Passive Tags?

How to choose the proper UHF RFID tags? For most people, it is difficult and intricate. The selection process starts with the RFID chip, which is the core of tags. Then you should select the RFID inlay. Last, you must choose the right carrier according to your application.

Here are some common UHF RFID tags as follows, they meet various applications in their distinct way.


UHF ABS Tag is durable and has good RF performance. It is suitable for warehouse pallets, equipment inspection, asset management.

UHF Animal Ear Tag

UHF RFID Animal Ear Tag is designed to track and manage large or medium size livestock or animals. It often used in animal husbandry.

UHF Car Light Label

The UHF Headlight Tag is transparent and has a adhesive layer. It can be attach to the headlight of the vehicle to track and identify the car.

UHF Ceramic Tag

RFID Ceramic Tag works well on metal surfaces. It is made of rugged ceramic material. Because it is fragile, it is an ideal solution for Anti-counterfeiting.

UHF Jewelry Tag

UHF Jewelry tag is designed to automatically track the retail, wholesale, or storage of jewelry. It is an efficient way for jewelry management.

Blank UHF RFID Sticker

UHF RFID Sticker is often used in library management. It has a back glue layer and can be easily attached to objects. It is a cost-effective UHF RFID solution.


The UHF Headlight RFID tag is predicated on passive UHF technology. The tag doesn’t contain A battery and is maintenance-free.

UHF Silicone Laundry Tag

UHF silicone RFID laundry tag is soft and durable. It can withstand high temperatures and harsh environments. It is widely used in laundry industry.

UHF Tire Label

UHF RFID Tire Tag is designed for vehicle tire management and tracking. It is sealed with the same base material as the tire, very durable.
