Number of data characters in a bar code between the start and stop
characters, not including those characters.
A bar code or symbol in which all spaces within the symbol are parts
of characters. There are no intercharacter gaps in a continuous code.
The absence of gaps allows for greater information density.
An area within a scanner's field of view, in which specular reflection
may prevent a successful decode.
To recognize a bar code symbology (e.g., UPC/EAN) and then
analyze the content of the specific bar code scanned.
A decoding scheme that converts pulse widths into data
representation of the letters or numbers encoded within a bar code
symbol.
The range between minimum and maximum distances at which a
scanner can read a symbol with a certain minimum element width.
A bar code or symbol in which the spaces between characters
(intercharacter gaps) are not part of the code.
A binary bar code symbology representing each character by a group
of five bars, two of which are wide. The location of wide bars in the
group determines which character is encoded; spaces are
insignificant. Only numeric characters (0 to 9) and START/STOP
characters may be encoded.
European Article Number. This European/International version of the
UPC provides its own coding format and symbology standards.
Element dimensions are specified metrically. EAN is used primarily in
retail.
Generic term for a bar or space.
Total linear dimension occupied by all characters of a code pattern,
including start/stop characters and data.
ENQ software handshaking is also supported for the data sent to the
host.
Flash memory is responsible for storing the system firmware and is
non-volatile, if the power is interrupted in the system.
A computer that serves other terminals in a network, providing such
services as computation, database access, supervisory programs,
and network control.
