Scanning methods refer to techniques used to capture and analyze data from various sources. These methods can include optical scanning, where physical documents are converted into digital formats, and barcode scanning, which reads information encoded in barcodes for inventory management. Another common scanning method is magnetic resonance imaging (MRI), used in medical settings to create detailed images of the body's internal structures. Each method serves specific purposes, enhancing efficiency and accuracy in data collection and analysis across different fields, including healthcare, retail, and document management.
