GS1-128 is commonly known as Code 128 or EAN-128.  It encodes all 128 'ASCII' characters and it also includes a check digit. It is more compact than other similar barcodes (e.g. Code 39) and is thus preferred for small items.

A special non-data Function1 character may be included after the start character, or omitted. It can be recognized by scanner software as a signature feature of these types of barcode – useful when an object bears several barcodes.
