CODE - A small white label with closely spaced black stripes that can be read by a computer. Bar codes on books and on your student identification card are used to charge out books from the library.
A horizontal band of colour or metal on the field of a flag. In heraldry it is sometimes regarded as a diminutive of fess, however, it is rarely borne singly and heraldic use frequently suggests that it should be about one-fifth the width of the field. In vexillology fess and bar are regarded as almost synonymous, with the difference that a fess is confined to the centreline of the field, whereas bar is not.
