Telepen
Telepen was devised by George Sims, Managing Director of SB Electronic
Systems Limited, in early 1972, this is the only symbology to directly rep-
resent the full ASCII character set without shift characters.Telepen carries
the double-density numeric-only mode and is very compact. The Telepen
symbol is up to 8 ASCII characters or16 digit per inch, and is easy to
print. It has a fixed 3:1 ratio, with a tolerance at least 0.4x. This symbolo-
gy is extremely secure, with negligible risk of misreading. It is supported
by most leading manufacturers.
UPC (Universal Product Code)
The UPC (Universal Product Code) is the symbology used throughout the
grocery and retail industries. This bar code symbology contains two pieces
of numerical information encoded on the bar code, producer identifica-
tion, and product identification information.
The UPC symbol is 12 characters long. The first character of the UPC
symbol is a number system character, such as “0” for grocery items and “3”
for drug- and health-related items.
The UPC symbology is for retail environments such as grocery stores, con-
venience stores, and general merchandise stores.
Some retail items are so small that a standard UPC bar code cannot fit on
the packaging. When this occurs there is a permitted shorter version of the
UPC symbology, referred to as UPC-E. UPC-E is six characters long
(eight including number system and check digit), approximately half the
size of a standard UPC bar code.
