OCR Check Character

You may want to print and verify a check character in order to

enhance the security of your OCR application. The AS-9500 can

be programmed for almost any type of check character. A number

of presets are provided for common check character uses (e.g.,

modulo 10 and modulo 36).

Scan the OCR Modulo 10 or OCR Modulo 36 Check Character

bar code to specify the type of check character used in the OCR
strings you’re scanning. The imager will then only read OCR

character strings with a valid check character. The AS-9500

transmits the OCR data without the

check character data. You must specify the location of the check

character in the template with a c.

Example: You need to read any combination of seven digits, with

a modulo 10 check character in the eighth position. The template

would be: dddddddc

To create this template, you would enable the OCR-A font. Scan

the Modulo 10 Check Character symbol. Then scan the Enter

OCR Template symbol, and scan the d from the OCR

Programming Chart seven times, and scan the c once. Scan Save

OCR Template . This template will let you read any combination

of six digits with a correct check character after. (If the check

character is invalid, the imager will issue an error beep.) For

example, the following string could be scanned:

and the output would be: 0123456
