OCR-B is an industry-standard optical character recognition typeface used on checks, barcodes, and other applications where accurate machine reading is crucial. Derived from OCR-A, it was among the very first typefaces readable by both humans and computers. Designed by Adrian Frutiger in 1968, it pushed the limits of character recognition at the time. OCR-A was much easier on computers, but proved cumbersome for humans. OCR-B was more natural for humans, however, and survives today to a greater extent than ORC-A. Modern OCR technology allows for accurate recognition of any character printed in a regular fashion. However, OCR-B is still in heavy use due to its high accuracy and relative elegance. You can see OCR-B at the bottom of any modern barcode. The typeface was refined and expanded in 1979 to include the full ASCII character set, and has not been altered since. It is accepted as ISO standard 1073/II-1976 (E).
