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.
