About Scanner

A scanner is an electronic device used to convert physical data or images into a digital format. It is primarily used for digitizing documents, photos, barcodes, QR codes, or other physical objects, making it possible to input them into a computer. Scanners typically use optical sensors to read the subject and process that information into digital data. This digital data can be saved as an image or converted into editable text using optical character recognition (OCR) software. There are several types of scanners, with the most common being flatbed scanners and film scanners. A flatbed scanner is a type where documents or photos are placed on a flat surface for scanning. It is known for its ease of use and high resolution. A film scanner is used to scan negatives or positives and is particularly useful for digitizing photographs or films. Scanners are used in various fields, including document management in offices and homes, digital archiving, photo editing, and security applications. In recent years, new technologies such as 3D scanners have emerged, which allow for the digitalization of three-dimensional objects. This technology is being used in industries such as manufacturing and healthcare.
