2.) what it is for...
MICR provides a secure, high-speed method of scanning and processing information, usually used by used by banks. Numbers and characters found on the bottom of checks (usually containing the check number, sort number, and account number) are printed using Magnetic Ink.

4.) what is the technology behind it...
To print Magnetic Ink need, you need a laser printer that accepts MICR toner.
When a document that contains this ink needs to be read, it passes through a machine, which magnetizes the ink and then translates the magnetic information into characters.

OCR: Optical Character Recognition
1.) what it is...
The OCR is a software that processes scans of source material and differentiates between images and text and determine what letters are represented in the light and dark areas.

2.) what it is for...
Used to make lengthy documents quickly available electronically. In libraries, it frees acres of storage space once given over to file cabinets and boxes full of paper documents.

4.) what is the technology behind it...
Older OCR systems match scanned images against stored bitmaps based on specific fonts. The hit-or-miss results of such pattern-recognition systems helped establish OCR's reputation for inaccuracy.
Today's OCR engines add the multiple algorithms of neural network technology to analyze the stroke edge, the line of discontinuity between the text characters, and the background so it can average the light and dark areas.

OMR: Optical Mark Recognition
1.) what it is...
Optical Mark Recognition (OMR) is the technology of electronically extracting intended data from marked fields, such as checkboxes and fill-in fields, on printed forms. It is generally distinguished from OCR by the fact that a recognition engine is not required.

2.) what it is for...
Optical Mark Recognition lets you define check box regions on scanned images. OMR is very fast and can be used for a variety of applications:
* Business reply mail
* Simple surveys
* Separate multi-page documents
* Document routing control
* Verify presence of signatures

4.) what is the technology behind it...
OMR technology scans a printed form and reads predefined positions and records where marks are made on the form (e.g. “bubble sheet”).
