You read it right. It’s possible to scan an image, such as a barcode, from the screen of a smartphone. You may ask why you would want to do that … but imagine for a minute the possibilities. What if your library patrons could have their library card barcode on their phone? The Swiss Army Librarian has already conducted an easy experiment to see if this is possible. Check out the results here.
Why not take this technology a step further. What if your user had the barcode or QR code of the book that they were looking for ready to go on their smartphone so that when they got to the library they could simply scan their phone and be pointed in the direction of the resource? The possibilities are endless.
