On-metal tag

An on-metal tag is a specially designed RFID tag intended for direct attachment to metal surfaces. Metal has a strong effect on radio fields and can interfere with signal transmission or significantly reduce the read range. Through a modified structure with suitable material layers, an on-metal tag reduces these effects and enables reliable identification on metal containers, tools or components. Such tags are particularly relevant where labels must function permanently on metal under industrial conditions and support stable object tracking. The correct choice and positioning of the tag largely determine whether metal objects can be detected reliably during ongoing operations.
