Instead of a single line, these labels can be read both vertically and horizontally.
How do barcodes work what information is stored on them?
In a nutshell, a barcode is a way to encode information into a visual pattern (those black lines and white spaces) that a machine (a barcode scanner) can read. … A barcode scanner will read this pattern of black and white bars and translate them into a line of test that your retail point of sale system can understand.
