Magnetic Ink Character Recognition

Magnetic Ink Character Recognition

MICR (Magnetic Ink Character Recognition) bezeichnet eine spezielle Variante der Erkennung von Zeichen (OCR) wie sie vor allem in den USA zur Verarbeitung von Schecks verwendet wird. Hierbei werden einerseits die Ziffern in einem speziellen Zeichensatz namens E-13B gedruckt. Darüber hinaus sind der für den Druck verwendeten Tinte magnetisierbare Eisenoxid-Partikel beigemengt.

Mittels eines magnetischen Lesegerätes können diese Zeichen mit einem deutlich höheren Erkennungsgrad und einer höheren Verarbeitungsgeschwindigkeit verarbeitet werden, als dieses bei klassischen OCR-Verfahren möglich wäre.
