ptical scanning techniques and magnetic scanning techniques are used to convert hard copy documents or images into a digital format for input into a computer system. Here are three different optical scanning techniques and two magnetic scanning techniques, along with an example for each:
Optical Character Recognition (OCR): OCR is a technique used to convert printed or handwritten text on paper documents into digital text that can be edited, searched, and stored electronically. OCR technology uses pattern recognition to identify characters in scanned images and then translates them into digital text. An example of OCR is the process of scanning a physical book into an e-book format.
Optical Mark Recognition (OMR): OMR is a technique used to read pencil or pen marks made in specific areas on paper forms. OMR technology detects the presence or absence of marks in specific fields, such as checkboxes, bubbles, or grids, and converts them into a digital format that can be processed by a computer. An example of OMR is the process of scanning paper-based surveys that respondents fill in by filling out bubbles or checkboxes.
Optical Character Verification (OCV): OCV is a technique used to verify the accuracy of printed or handwritten text in scanned images by comparing it to a reference database. OCV technology uses image analysis and pattern recognition to identify characters in scanned images and then compares them to a known reference database of correct characters. An example of OCV is the process of verifying the accuracy of serial numbers on manufactured goods during quality control checks.
Magnetic Ink Character Recognition (MICR): MICR is a technique used to read magnetic ink characters printed on paper documents such as checks. MICR technology reads the magnetic ink characters and converts them into a digital format that can be processed by a computer. An example of MICR is the process of depositing a check by scanning it at an ATM.
Magnetic Stripe Reader (MSR): MSR is a technique used to read data stored on magnetic stripes on credit cards, ID cards, and other similar cards. MSR technology reads the magnetic stripe and converts the data into a digital format that can be processed by a computer. An example of MSR is swiping a credit card at a point-of-sale terminal to pay for a purchase.
These are just a few examples of the many different scanning techniques that are used for input. The choice of scanning technique depends on the type of document or image being scanned, the accuracy required, and the intended use of the digital data.
