Telecom

The Telecom industry adopted a standard in 2001 which utilizes Micro PDF 417 for high density information content, along with a special version of Code 39 which provides backward compatibility with existing systems. The Code 39 symbol includes a special “link” character which indicates the presence of the Micro PDF 417 symbol to new reading systems which are programmed to recognize the new format. This label specification is documented in a Telcordia documnet, GR-383-CORE. Later, the use of Data Matrix was also adopted.

The following verifiers can be used for Telecom labels.
