OCR (Optical Character Recognition) is a technology used to directly input printed or handwritten text into a computer by scanning and converting it into machine-readable text. In contrast, OMR (Optical Mark Recognition) reads marks on forms, and MICR (Magnetic Ink Character Recognition) is used for reading magnetic ink characters, commonly in banking.
