Idea Summary
Extend the page designer, so it is directly possible to display a data item as a "barcode", similar to “qrcode”.

Use Case
For displaying data it is possible to create a QR-code item in the page designer. Barcodes are quite common on product labels, so the direct support for barcodes in the page designer makes life easier. 

Preferred Solution (Optional)
Add a new itemtype “barcode” or add  a selection for the barcodetype to the itemtype qrcode.
