MICR Commands and Parsing
These commands control the Magnetic Ink Character Recognition (MICR)
check reader, including how it parses the character strings on checks. This
section explains these commands.
The section that follows, “MICR Parsing,” describes how to create a parsing
format and how to create and maintain an exception table. If you would like a
copy of a software utility that performs these functions rather than developing
your own program using the command codes described in this section, please
contact Unisys. The software utility can be used as provided or can be
incorporated into your own application.
MICR Commands
