CODABAR

Codabar is ideal for applications that contain mostly

numeric symbols that may vary in length from bar code to

bar code.  It can encode the digits from 0 to 9, the char-

acters “-”(dash), “$”(dollar sign), “:” (colon), “/” (forward

slash), “.” (period), and “+” (plus) as well as start/stop

characters A through D.

One optional checksum is automatically appended as

the least significant digit in the bar code data directly

before the stop character.  The bar code symbology

specification contains all the information on calculating

the checksum.  As a short example, our data will be

“A37859B” where A and B are start/stop characters.  The

characters 0 through 9 are assigned the numerical values

0 through 9 respectively.  “-” is 10, “$” is 11, “:”is 12, “/” is

13, “.” is 14, “+” is 15, and start/stop characters A B C and

D are 16, 17, 18, and 19 respectively.

Step 1:

Add the numerical value of all the characters.

16 + 3 + 7 + 8 + 5 + 9 + 17 = 65.

Step 2:

Divide this number by 16 and use the remain-

der, or modulo.  In our example, this is 1

Step 3:

Subtract the modulo from 16.  This is the small-

est number that can be added to the sum in step 1 to

make a multiple of 16.  (65 + 15 =80.  80 /16= 5)

Therefore, the check sum for our example is 15.

Step 4:

The character that corresponds to 15 is “+” and

is added in before the stop character.  Our final bar

code looks like “A37859+B”.
