The scanner apps on these android devices make use of OCR (Optical Character Recognition). It is the mechanical or electronic conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document or photo of a document. With OCR you can be able to copy or manipulate text from the scanned document.
