Companies using different types of bar codes in their warehouse (for example ‘simple’ CODE39 for warehouse location or item bar codes, and EAN128 bar codes for serial/batch items) could encounter the problem that a non-EAN128 bar code would be treated and decoded as an EAN128 bar code. That would lead to undesired messages like ‘item not found’. This is because when scanning a bar code, the software could not tell the difference when scanning a CODE39 bar code or an EAN128 bar code.
Sample of a CODE39 bar code and an EAN128 bar code:
From product update 399, E-WMS will support ‘Bar Code Indentifier’. This is a setting on hand terminals whichs add an extra character as prefix to each scan, where a unique character will be put in for each type of bar code. For example, when scanning an EAN128 bar code, the scanner will put a “K” in front of the scanned text, where the character “B” would be added when scanning a CODE39 bar code. So now E-WMS knows when to start EAN128 decoding !
