21.5 The usage of EAN-128 barcode in scales.
The EAN-128 barcode standard has been created to provide a worldwide
standard for exchanging simple data between enter prices. Other codes include
data without marking what they include. EAN-128 includes data with all
information about them.
For example, when coding 17,21 kg as 1721 an application does not know if it
is a price, time or mass. Even if the application can identify this field as weight
it has no information about unit and point (1721 kg or 17.21 g).
It is important that everybody can decode the information without any additional
modifications. EAN-128 standard solves this problem. It includes a list of
"Application Identifiers". Every identifier carries a message to inform a system
about the data type and format. E.g. 310 identifier indicates for the net mass in
kg. The next digit in this identifier outlines the point position, then the following
6 digits outline a weight.
Application Identifiers.
