Circus™ On-Metal tags have been specifically designed to work on metallic objects. They open the door to all applications involving the tagging of metal surfaces that need to be identified or interacted with, such as metallic parts, tools, machines, spare parts and even domestic items.

In its Circus On-Metal tags, Avery Dennison Smartrac combines flexible ferrite materials with a performance-optimized antenna design. The super-thin ferrite-based inlay is produced by applying a layer of ferrite material to the inlay, which isolates the magnetic field from the metal surface. Ferrite redirects the reader’s inductive field, and prevents energy from being wasted as heat within the metallic surface.

The flexible ferrite-based NFC inlays are suitable for roll-to-roll manufacturing processes, which make onward processing much easier and more cost-effective, and allow converters to overprint the inlays if required.

Circus On-Metal is equipped with the NXP NTAG213 IC. This chip offers (UID) mirror functionality that enables the IC’s serial number to be mirrored as part of its encoded data, and identifies unique reads from the application perspective. The product is less than half a millimeter thicker including the added ferrite layer.
