OCR Check Character
You may want to print and verify a check character in order to enhance the security of your OCR application. The ZB-3062 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 ZB-3062 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
OCR Modulo 10 Check Character
Scan this symbol to program the OCR template for a simple modulo 10 checksum of the digits 0 through 9.
OCR Modulo 36 Check Character
Scan this symbol to program the OCR template for a simple modulo 36 checksum of the digits 0 through 9 and the letters A through Z.
