Answer 2

Optical mark recognition (OMR)

Optical mark recognition (OMR) is an electronic method of gathering human-handled data by identifying certain markings on a document. Usually the optical mark recognition process is achieved with the aid of a scanner that checks the transmission or reflection of light through the paper; places having markings will reflect less light than the blank paper, resulting in less contrasting reflectivity.

Optical mark recognition is also known as optical mark reading or, more commonly, by the brand name Scantron.
