Definition - What does Microstamping mean?
Microstamping is a form of technology that uses precision lasers to imprint or etch tiny (microscopic) unique identifiers on a material for tracking or recording purposes.
Microstamping is often preferred to other forms of material identification due to its corrosion resistant properties. The presence of the etching on a microscopic level makes its response to corrosion causing elements virtually nil.
Corrosionpedia explains Microstamping
Microstamping is sometimes used in law enforcement and jewelry applications to track gun and jewelry ownership in attempts to thwart gun-related crimes and jewelry theft. Microstamping is used in manufacturing so that specific parts can be traced to their time and location of origin.
