Bar codes

Bar codes are composed out of parallel vertical dark and white stripes of strictly determined width and strictly determined mutual proportion between spaces. Such bar codes are transferred by special readers (e.g. at cash registers) into digital codes which permit immediate and accurate identification of a particular good. Bar-coded labels are made either on a roll or on a sheet of paste or non-paste paper.
