Overview and Applications of RFID Anti-Metal Tags

May. 27, 2024

The Internet of Things (IoT) industry has been widely applied across various sectors. Currently, in IoT application fields such as warehouse management, logistics sorting, asset management, and intelligent inspection, nearly 90% of the managed items lack self-identification capabilities. As a typical representative of automatic identification technology, electronic tags have a promising development prospect and can create significant value for the development of the IoT industry.

However, in certain special application scenarios, such as metal environments and metal product identification, the signals of general electronic tags are shielded and interfered with, making data collection difficult or even impossible. In response to these usage environments, anti-metal electronic tags have emerged.


  1. ABS Anti-Metal Tags: ABS anti-metal tags are made of high-temperature-resistant industrial ABS plastic, metal shielding materials, epoxy resin encapsulation, and ultrasonic welding. They have characteristics such as sun resistance, water resistance, and high-temperature resistance. These tags are widely used in logistics management, luggage, pallets, containers, shelves, equipment, and fixed asset management.


  2. PCB Anti-Metal Tags: PCB anti-metal tags can be directly attached to metal surfaces and are suitable for installation on vehicle license plates. They are also suitable for outdoor power equipment inspection, iron tower and utility pole inspection, elevator inspection, pressure vessel cylinders, various household electrical devices, product tracking, asset management, logistics management, and automotive parts process management.


  3. Flexible Anti-Metal Tags: Flexible anti-metal tags have a certain degree of flexibility and can be printed. They are well-suited for metal surfaces, offering excellent anti-metal properties, superior performance, good directionality, and long reading distances. These tags are suitable for attachment to curved metal surfaces such as gas cylinders and can be applied in RFID asset management, cylinder tracking, traffic control, logistics management, and hazardous materials management.

In summary, selecting appropriate anti-metal tags is a prerequisite for ensuring the effective application of RFID systems in metal environments.
