When I see people in banks with taped bundles of notes I wonder if they’d miss one or two.
Today’s invention is a way to ensure that there is the correct number of notes in such a bank-fresh wad.
Each of the notes would be printed with smoothly sequential images of a face in motion (I rather like the idea of asking the queen to say “These are all tenners”).
Since we are hyper-sensitive to facial movements, the bundle of notes could be riffed, like a child’s flick-book, and any discrepancies would indicate an attempt at short-changing.
