At present, the development of UHF anti-metal tags shows three obvious trends: small size, flexible structure, low cost.

1. Small size
The size of previous UHF anti-metal tag is too large. It is not conducive to the expansion of application areas. With the development of intelligent manufacturing and wisdom medical, the market demand for high-performance miniaturized anti-metal tags gradually increased. This kind of product is suitable for the integrated management, identification and traceability of small and micro metal devices. Such as: Medical devices, metal tools, aerospace, etc.

2. Flexible structure
Conventional PCB and ceramic hard tags can not be bent and kneaded, can only be applied to flat surfaces. The strength of the material itself makes it impossible to achieve tampering, so it is often recycled and can not meet the market demand for anti-metal tamper labels. But the anti-metal label of flexible structure not only can be bend also adapt to more folding Angle and curved applications. Combined with the characteristics of the chip, the changes of the structure, also can achieve tamper function. Make up the insufficiency of hard tags, also expand the application space.

3. Low cost
Hard metal tags mainly are PCB antennas and ceramic antennas, the raw material costs are high. And in the package mainly are SMT (surface mount) or COB, manufacturing costs are still high. If using flexible anti-metal tags, the cost of raw materials is relatively low. Roll to roll mass production, the cost can be greatly reduced.
