Answer:
The difference between Scanner and Optical mark reader are as follows-
- A scanner is an electrical device that captures pictures from physical objects and converts them into digital forms that may then be stored in a computer and viewed or manipulated using software programmes.
- OMR is an electronic way of acquiring human-handled data by recognising certain marks on a document. Optical mark identification is often accomplished with the use of a scanner that checks the transmission or reflection of light through the paper; locations with marks will reflect less light than blank paper, resulting in less contrasted reflectivity.
- There are several types of scanners with varying resolutions available. Scanning is widely regarded as the most cost-effective and dependable method of delivering pictures in the field of electronic data transmission.
- Optical mark identification is sometimes known as optical mark reading or, more colloquially, Scantron.
- Modern scanners are designed for speed and efficiency. It also comes with simplicity of usage and convenience.
- Optical mark recognition technology rapidly and accurately pulls meaningful data from marked fields such as fill-in fields and checkboxes.
- One of the most significant advantages of scanning is the ability to replace physical files/forms with digital ones. Along with conserving physical space that would otherwise be required for storage, employing a scanner provides environmental benefits.
- OMR can process hundreds of thousands of physical documents every hour and has a 99% accuracy rate. One prominent example is the usage of standardised forms in schools, in which pupils must fill out a specified mark on the page, which serves as a mark for the optical mark recognition algorithm.
