Codabar
Codabar can encode the digits 0 through 9, six symbols (-:.$/+), and the start/stop characters
A, B, C, D, E, *, N, or T. The start/stop characters must be used in matching pairs and may
not appear elsewhere in the barcode. Codabar is used in libraries, blood banks, the overnight
package delivery industry, and a variety of other information processing applications.
UPC-E
The UPC-E is a 6 digit-shorter version of UPC-A. This barcode is about half the size of the
UPC-A for the same product number. Only a subset of the numbers that can be encoded with
UPC-A can be encoded with UPC-E. It is used on products with small packaging.
Maxicode
MaxiCode is a fixed-size code which holds up to 93 data characters. The symbol
is composed of a central bulls-eye locator and offset rows of hexagonal elements; the overall
dimensions of the symbol are approximately 1.11 x 1.054 inches. Each element measures
0.035 x 0.041 inches. Created by United Parcel Service, the MaxiCode symbol was designed
for quick automated scanning of packages on high-speed conveyor lines (special cameras
can read a MaxiCode on a carton travelling at up to 500 feet per minute). A 2-D scanner is
required; MaxiCode cannot be read using an ordinary linear barcode scanner.
PDF 417
PDF 417 is a two dimensional barcode which allows large amounts of text and data to be
stored securely and inexpensively into a small space. The PDF 417 symbology can also
withstand damage without causing loss of data. Error correction is more advanced in the PDF
417 than one dimensional barcodes. More than one thousands characters of information can
be encoded into this type of barcode.
Data Matrix
Data Matrix from
Acuity CiMatrix
(look
here
for more information) is a 2-D matrix code
designed to pack a lot of information in a very small space. A Data Matrix symbol can store
between one and 500 characters. The symbol is also scalable between a 1-mil square to a
14-inch square. That means that a Data Matrix symbol has a maximum theoretical density of
