ferent 2D codes have been standardized by AIM. These include the
code types Aztec, QR code, Maxi code, Dot code A, Code one, and the
Data Matrix Code in the ECC000-140 and ECC200 variants (Fig. 3.1).
You can also download code specifications for several stacked barcodes
and combined code types from the AIM website (www.aimglobal.org).
Data Matrix ECC200 has been implemented the most so far.
3.2.2 Application standards
In addition to the technical standards, several applications are also
based on the Data Matrix Code.
On the one hand, subsequent to NASA’s activities, the US Department
of Defense, DoD, has decided to prescribe a binding requirement on
its suppliers that all expensive, serialized, inventoried expendable
components that are decisive for the use or placing of an order are
identified with coded data content according to the prescribed regulations
based on the Data Matrix Code ECC200. This specification is
known as the UID (Unique Identification) MIL-STD-130 and is being
introduced worldwide following several additions to the specification.
Also the Data Matrix Code ECC200 contains a unique identifier
worldwide.
On the other hand, Data Matrix Code was approved by GS1 as an additional
option for use as an EAN code. The so-called EAN Data Matrix is
viewed as especially appropriate for use on small items, for example
in the jewelry or cosmetics sectors.
In the healthcare sector, the EHIBC (European Health Industry Business
Communication Council) and GS1 force the use of different processes
when standardizing the coding standards, each of which pro-
