![]() CMC-7 can also produce superficially successful, but incorrect, scans of upside-down MICR lines. ĬMC-7 has a barcode format, with every character having two distinct large gaps in different places, as well as distinct patterns in between, to minimize any chance for character confusion while reading magnetically however, these bars are too close and narrow to be reliably recognised at a typical scan resolution if falling back to optical scanning. The control characters after the numerals are (from left to right) S I ( internal), S II ( terminator), S III ( amount), S IV, and S V ( routing).ĬMC-7 includes 10 numeric digits, 26 capital letters, and 5 control characters: S I ( internal), S II ( terminator), S III ( amount), S IV (an unused character), and S V ( routing). These alternative representations were added for interoperability with Siemens and Océ printers. IBM code page 1032 extends code page 1001 by adding alternative encodings for transit at 0x5C, 0x7A and 0xC1, on us at 0x4C, 0圆1 and 0xC3, amount at 0x5B, 0x5E and 0xC2 and dash at 0圆0, 0x7E and 0xC4, in addition to a zero-width space at 0x5A. For EBCDIC, IBM code page 1001 encodes digits in their usual EBCDIC locations, transit as 0xDB, on us as 0圎B, amount as 0xCB and dash as 0xFB. Prior to Unicode, it could be encoded according to ISO 2033:1983, which encodes digits in their usual ASCII locations, transit as 0x3A, on us as 0x3C, amount as 0x3B and dash as 0x3D. The E-13B repertoire can be represented in Unicode (see below). Compared to CMC-7, some pairs of E-13B characters (notably 2 and 5) can produce relatively similar results when magnetically scanned however, as a fallback if magnetic reading fails, E-13B also performs well under optical character recognition. This reference comes from the 4 characters: Transit, Onus, Amount, and Dash. ![]() In the check printing and banking industries the E-13B MICR line is also commonly referred to as the TOAD line.
