IEC
International Electrotechnical Commission. This international

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
represent 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.
