Does anyone know how a library scanning system works?
Just curious…like how does it gather all the information from the barcode and know to register it in the system??

Best answer:

The answer is, that the barcode doesn’t have ALL of the information. The barcode is just a scannable number. There will be a database where someone has registered the details of that book against the barcode. when you scan the barcode the returned number is cross referenced against the database. Some library systems may already have the information built into the system that they have from some standard source like the ISBN system so they wont have to manually add every book.
