CMC7 is one of two major Magnetic Ink Character Recognition (MICR) fonts used in the printing of checks and other payment documents. CMC7 is popular in Europe and South America, while the other main MICR font, E13B, is the standard in North America and much of Asia.
As you can see in the image at right, each character in the CMC7 font is actually its own specific barcode with two gaps and many smaller gaps, making the font well-suited for machine-reading purposes. However, depending on the resolution and the quality of the scan, these small lines can blend together or be difficult to pick up.
For a more complete discussion of the difference between CMC7 and E13B MICR fonts, see our educational article, Battle of the MICR Fonts.
