Concept: MICR Encoding

David Michael Hillbun -

MICR lines consist of a series of digits along with 6 additional symbols that do not necessarily have representation in the Unicode character set. These symbols are the transit symbol, the on-us symbol, the amount symbol, the dash symbol, the space symbol and the error symbol. Unfortunately, there is not a single standard for representing these symbols; as a result, multiple encodings have become common. ACHeck21 Micro supports the 2 most common of these formats: TOAD and bcd-encoding. The table below shows the details of these 2 encodings:

All MICR lines are stored internally by Micro in the bcd format.
