While the overall concept of product tracking using bar codes is not new, the automated tracking of product down to the individual part and component level has proven to have an impact on the bottom-line. The most direct way to ensure complete quality control of the production process is to directly mark a part with a machine-readable code and track it through its entire life cycle. This is called Direct Part Mark Identification (DPMI). Recognizing the benefits of direct part marking, many industry associations have already established standards for marking individual components for a variety of applications.

The EIA, SEMI, AIAG, DoD (UID), ATA and the IAQG SPEC 2000 have all adopted DPMI standards for applications in their industry. Additionally companies are using direct part marking for their own internal applications. DPM can be used to optimise line performance, identify defects, increase first-pass yield and as result, reduce the costs of manufacturing. Manufacturers also rely on DPMI for identifying incoming parts for maintenance and returns, resolving warranty issues, counterfeit parts, and liability claims as well as tracking high-value components to prevent theft.
