ICR 803 Bar Code Scanner BAR CODE MANUAL

Adding an OCR Check Character
You may want to print and verify a check character in order to enhance the security of your OCR
application. The OEM Engine 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 OEM Engine 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 F: You need to read any combination of 7 digits, with a modulo 10 check character in the 8th
position. The template would be:
dddddddc
To create this template, you would scan the Modulo 10 Check Character symbol. Then scan the Enter
OCR Template symbol, scan the d from Appendix D 7 times, and scan the c once. Scan Save OCR
Template. This template will let you read any combination of 6 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
OCR Modulo 10 Check Character
01234569
Scan this symbol to program the OCR template for a simple modulo 10 checksum of the digits 0
through 9.
