FAQ

It is usually letters and numbers. For some barcodes you can choose a specific set of characters(symbology). This information usually represents some description of an item on what barcode is placed.

It is usual to be about 25 characters for 1D barcode and about 2000 for 2D one. Of course the more characters you encode the bigger is barcode. 1D barcode could became impractically wide if it is more than 15 characters encoded.

It is a combination of contrast marks that scanner can read and decode. For 1D barcode it is black and white vertical lines of different thickness. For 2D it is usually a pattern of square dots. Scanner uses some algorithms to decode those patterns into a form suitable for user.

For some types of barcodes it is important. For ITF-14 size is required to be 142.75 mm wide and 32 mm high. For EAN-13 it is required to be 37.29 mm wide and 27.85 mm high.
