MetalPal：UHF On-Metal RFID Labels for Metal-Intensive Environments
Turning metal from an RFID barrier into a dependable tracking surface—engineered to remain stable where heat, humidity, and metal converge.
Metal-intensive environments are among the most demanding conditions for UHF RFID deployment—especially when combined with high temperature and high humidity. Metallic surfaces can detune antennas, absorb RF energy, and disrupt backscatter signals, leading to inconsistent read ranges, frequency drift, blind spots, or complete tag failure. These effects become significantly more severe in real-world applications such as machinery, tools, containers, mobile medical equipment, and industrial assets, where assets are exposed to heat, moisture, frequent movement, and long-term outdoor operation.
MetalPal UHF on-metal labels are engineered to remain electrically stable beyond laboratory conditions.
Validated under high temperature and high-humidity environmental reliability testing, MetalPal maintains stable electrical characteristics and consistent read performance across metal surfaces. The design ensures stable read sensitivity and predictable read range across a wide variety of metal surfaces. A structurally robust construction resists warping and performance degradation, even in outdoor deployments exposed to heat, humidity, and changing weather. At the same time, a compact form factor allows easy integration into space-constrained equipment and dense factory layouts. This enables reliable RFID asset tracking across both indoor metal-dense facilities and outdoor operational environments, where conventional metal labels often struggle to perform.

MetalPal – Slim
MetalPal – Slim features a approximately 20% smaller form factor, making it easy to deploy across a wide range of metal assets and space-constrained installation scenarios. Its slim design allows flexible placement on compact equipment, tools, and mobile assets that are typically challenging to tag with standard on-metal labels.
Built on a ferrite-based structure, MetalPal – Slim is engineered for reliable outdoor operation, maintaining consistent performance even in high-humidity environments and changing weather conditions. Unlike foam-based constructions that can be affected by moisture over time, ferrite provides long-term structural stability and predictable RF behavior. With broadband capability and stable read sensitivity, MetalPal – Slim enables dependable UHF RFID asset tracking across diverse metal surfaces, delivering consistent data capture wherever durability and space efficiency matter most.

Tag Built to Survive Harsh Environment
RFID Transponders from large to small are put to work to enhance the visibility of progress in different stages. Chances are the whole process might happen under extreme high/low temperature. Any reading failure would stop the production flow and decrease its efficiency. Based on the know-how and expertise in material science, SAG builds hard tag to survive extreme working conditions without compromise to reading performance.
Miniaturization to Fit Small Items
For an item with limited space to apply a tag, SAG has a variety of miniaturized tags to go with small parts for asset management or machine-to-machine communication. Also, NFC Ferrite Tags (the smallest in 4x2mm) are for both on-metal and non-metal use cases.
