Optical scan technology

Optical scan technology is a method used to read and process information, typically from paper documents, by using light. It works by scanning the document and converting marked areas, like filled-in bubbles on a test or ballot, into digital data. The scanner captures the images, and software analyzes these images to determine the selections made. This technology is widely used in voting systems, standardized testing, and data collection, offering efficiency and accuracy in gathering information. It eliminates manual entry errors and speeds up the counting process, ensuring reliable results in various applications.
