Self-Checking Code A symbology that uses a checking algorithm to detect encoding errors
within the characters of a bar code symbol.
Shared Key Shared Key authentication is an algorithm where both the AP and the
MU share an authentication key.
Space The lighter element of a bar code formed by the background between
bars.
Specular Reflection The mirror-like direct reflection of light from a surface, which can
cause difficulty decoding a bar code.
Start/Stop Character 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.
Subnet Mask A 32-bit number used to separate the network and host sections of an
IP address. A custom subnet mask subdivides an IP network into
smaller subsections. The mask is a binary pattern that is matched up
with the IP address to turn part of the host ID address field into a field
for subnets. Default is often 255.255.255.0.
Substrate A foundation material on which a substance or image is placed.
Symbol 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.
Symbol Aspect
Ratio The ratio of symbol height to symbol width.
Symbol Height The distance between the outside edges of the quiet zones of the first
row and the last row.
Symbol Length Length of symbol measured from the beginning of the quiet zone
(margin) adjacent to the start character to the end of the quiet zone
(margin) adjacent to a stop character.
Symbology The structural rules and conventions for representing data within a
particular bar code type (e.g. UPC/EAN, Code 39).
