RFID on metal refers to radio-frequency identification (RFID) tags which perform a specific function when attached to metal objects. The ROM tags overcome some of the problems traditional RFID tags suffer when near metal, such as detuning and reflecting of the RFID signal, which can cause poor tag read range, phantom reads, or no read signal at all.

The RFID-on-metal tags are designed to compensate for the effects of metal. There are several tag design methods to create ROM tags. The original method was to provide a spacer to shield the tag antenna

Antenna (radio)

An antenna is an electrical device which converts electric currents into radio waves, and vice versa. It is usually used with a radio transmitter or radio receiver...

 from the metal, creating bigger tags. New techniques focus on specialized antenna design that utilizes the metal interference and signal reflection for longer read range than similar sized tags attached to non-metal objects. RFID-on-metal transponders will continue to create new opportunities for users in a wide range of asset tracking and broader industrial applications. The main applications are asset tracking on servers and laptops in IT data centers, industrial manufacturing quality control and manufacturing, oil and gas pipeline maintenance, and gas cylinders.
The technology is evolving to allow transponders to be embedded in metal. The capability allows manufacturers to track small metal items from cradle to grave. The main focus for RFID inside metal is tool tracking, weapon tracking, and medical device quality control.
