■ What is a 1D code?
A 1D code, also called a bar code, bar code or barcode, is a linear font consisting of parallel bars and gaps of different widths; these bars and gaps usually stand for numbers or letters. The term code stands for the representation of data in binary symbols.
■ How is a 1D code decoded?
To decode a 1D code, you use a barcode reader or camera to read the width of the printed bars and the non-coloured gaps in between with the laser or LED. This is done by reflections of the light and dark gaps. The scanner transmits the character string to an IT system. This system can read and process the information encoded in the barcode.
