==Subheadings==

The Optical Character Recognition block has three subheadings within its character collection: OCR-A, MICR, and OCR.<ref>{{cite web|url=http://www.unicode.org/charts/PDF/U2440.pdf}title=Unicode Code Charts: Optical Character Recognition|work=The Unicode Standard, Version 6.3|accessdate=27 February 2014}}</ref>

===OCR-A===

The OCR-A subheading contains six characters taken from the [[OCR-A]] font described in the ISO 1073-1:1976 standard: U+2440 OCR HOOK, U+2441 OCR CHAIR, U+2442 OCR FORK, U+2443 OCR INVERTED FORK, U+2444 OCR BELT BUCKLE, and U+2445 OCR BOW TIE. The OCR bow tie is given the [[Unicode_character_property#Name|informative alias]] "unique asterisk".

===MICR===

The MICR subheading contains four characters standardized in the ISO 1004:1995 standard, from the [[magnetic ink character recognition]] E-13B font: U+2446 OCR BRANCH BANK IDENTIFICATION, U+2447 OCR AMOUNT OF CHECK, U+2448 OCR DASH, and U+2449 OCR CUSTOMER ACCOUNT NUMBER. The standard notes that "the Unicode character names include several misnomers" and gives [[Unicode_character_property#Name|normative alias]]es for two: U+2448 is MICR ON US SYMBOL, and U+2449 is MICR DASH SYMBOL. All four have informative aliases: "transit", "amount", "on us", and "dash" respectively.

===OCR===

The OCR subheading consists of a single character: U+2450 OCR DOUBLE BACKSLASH.
