Most voted "barcode" questions
Barcode is a graphical representation of numerical or alphanumeric data. The echodification (reading) of the data is performed by a type of scanner, which emits a red ray that runs through all the bars. Where the bar is dark, the light is absorbed; where the bar is clear (spaces), the light is reflected back to the reader. If the doubt is not about the "Barcode", do not use this tag, even if you are using the "Barcode" in your project.
