ENCODED AREA Total linear dimension occupied by all characters of a code
pattern, including start/stop characters and data.
ERROR CORRECTION In addition to error detection, the recovery capability of
PDF417 over missing, destroyed, or misdecoded codewords.
Error correction capability is based on the level of security (0
- 8) selected when the PDF417 label is printed.
EXTRANEOUS INK Ink in a scan area not intended to be there (i.e., tracking and
splatter).
FIRST READ RATE Percentage of correct readings obtainable by one pass of a
scanning device over a bar code.
FLASH Derived from EEPROM, this is a type of memory that holds
its content without power but must be erased in bulk — or
in a “flash.” Typically, these memory chips are less expensive
and provide higher bit densities.
GUARD BARS The start, stop, and center delimiting bars of UPC and EAN
symbols.
HOST COMPUTER A computer that serves other terminals in a network,
providing such services as computation, database access,
supervisory programs, and network control.
INTERCHARACTER GAP The space between two adjacent bar code characters in a
discrete code.
INTERLEAVED BAR CODE A bar code in which characters are paired together, using
bars to represents the first character and the intervening
spaces to represent the second.
INTERLEAVED 2 OF 5 A binary bar code symbology representing character pairs in
groups of five bars and five interleaved spaces. Interleaving
provides for greater information density. The location of
wide elements (bar/spaces) within each group determines
which characters are encoded. This continuous code type
uses no intercharacter spaces. Only numeric (0 to 9) and
START/STOP characters may be encoded.
