Optical codes

Codes and their fields of application

Four steps are required for complete traceability during production and beyond: Marking, Verification, Reading, Communication (MVRC). 

 

Marking is the application of the coding directly to the object.

Verification stands for checking the quality of markings on the object.

Reading is the reading in production or in case of service.

Communication includes securely transmitting and visualization of the reading results.  

 

Whether 1D barcode, 2D data matrix code or text recognition via OCR: Each technology has its specific strengths. For example, plain text recognition is used where information must also be legible for people, such as the best-before date. Siemens offers you proven products and systems for all these areas.

2D data matrix code

Compared to the barcode, the 2D data matrix code offers a higher storage capacity, more data security and a better reading rate in terms of viewing angle and illumination. These codes can be applied cost-effectively, e.g. together with shipping labels. In addition, they enable direct part marking (DPM) of products by laser, printing or nailing, which makes them particularly robust against external influences and has proven its worth especially in harsh industrial environments.

Text recognition (OCR)
