What is a 1D Barcode?
A 1D barcode is a visual black and white pattern, using variable-width lines and spaces for encoding information. That information – such as numbers or other keyboard characteristics – is encoded horizontally from left to right. 1D barcodes holds a limited number of characters, typically 20-25. In order to add more numbers, the barcode must be longer. 1D barcodes are the common lined barcodes you see on most consumer goods and products. 1D barcodes represent data by varying the widths and spacings of parallel lines.
The most familiar 1D barcodes are those common UPC codes found on grocery and consumer items. A 1D barcode depends on database connectivity in order to be meaningful; after a scanner reads the numbers in the code, they must be linked back to product or pricing date, or other information.
