device or method.
Reduced Space Symbology: A family of space efficient
symbologies developed by UCC.EAN.
Area intended to contain a symbol.
An electronic device used to scan bar code symbols and
produce a digitized pattern that corresponds to the bars and
spaces of the symbol. Its three main components are:
1. Light source (laser or photoelectric cell) - illuminates a
bar code.
2. Photodetector - registers the difference in reflected light
(more light reflected from spaces).
3. Signal conditioning circuit - transforms optical detector
output into a digitized bar pattern.
The scanner is energized, programmed, and ready to read a
bar code.
A method of programming or configuring parameters for a
bar code reading system by scanning bar code menus.
A symbology that uses a checking algorithm to detect
encoding errors within the characters of a bar code symbol.
Rotation of a bar code symbol on an axis parallel to the
symbol's length.
The lighter element of a bar code formed by the background
between bars.
The thickness of a space measured from the edge closest
to the symbol start character to the trailing edge of the
same space.
The mirror-like direct reflection of light from a surface,
which can cause difficulty decoding a bar code.
A 2-dimensional (2D) symbol with sequences of linear
(width-coded) data that are stacked one upon another (i.e.,
PDF417).
A pattern of bars and spaces that provides the scanner with
start and stop reading instructions and scanning direction.
The start and stop characters are normally to the left and
right margins of a horizontal code.
A foundation material on which a substance or image is
placed.
A scannable unit that encodes data within the conventions
of a certain symbology, usually including start/stop
characters, quiet zones, data characters, and check
characters.
The ratio of symbol height to symbol width.
The number of data characters per unit length; usually
expressed as characters per inch (CPI).
The distance between the outside edges of the quiet zones
of the first row and the last row.
