(I’m really interested to see what sort of ads this page gets assigned in light of the above title).
Today’s invention is stupidly simple. I spend quite some time, despite the present digital era, queueing at the library to borrow good old fashioned books made of good old fashioned tree.
It breaks my heart to see the librarians have to scan in the barcodes for all my books and then pick them all up again, one by one, and stamp the return-by date on every book. My invention today is simply to tape the scanner to the date stamp and do both jobs on each book in quick succession.
If you wanted a high tech solution, you could go for a passive display in each book, which the scanner would update automatically. I’d always go for the duct tape solution, myself but come to think of it -why can’t I just download my library books yet?
