NLS-Glossary

Barcodes have been a feature of the supply chain landscape for more than 40 years. Over that time, many types of barcodes have been developed and put into use in many industries all over the world.

Barcodes work by encoding data into a binary system that can be scanned and then decoded by specialized readers. A symbology is a set of rules that govern what kind of data is encoded and how. Hundreds of symbologies exist, having been developed and refined over decades as technology improves. Some symbologies have also been customized to meet the needs of a business or to conform to industry standards.

Two-dimensional barcodes are known under names like PDF417, or Codablock F. Such stacked or multi-row barcodes store information in two dimensions. Several stacked linear barcodes are used to encode the information.

Offset distance from the face of the sensor to the beginning of the measurement edge.                                                                                                                                                 

A batch number is encoded with AI 10. The format of AI 10 is “n2 + an..20”. This means the AI has two digits (10) followed by variable length data with maximum 20 characters.

is a measure of the rate of digital signal transmission in terms of transitions per second.                                                                                                                                                        

This indicates the number of symbols transferred in one second. The unit for this is Baud (abbreviated to Bd) or 1/s. If a symbol corresponds to one bit, then the baud rate is equal to the bit rate.
