This philosophy led Mactwin to develop GlueFusion; an ATM cash cassette with a built-in module for degradation by glue. Upon activation, GlueFusion glues all individual banknotes together in the blink of an eye, leaving nothing but a worthless, solid brick of paper. If anyone tries to peel off a single banknote, it will immediately tear into small pieces. The applied glue cannot be dissolved or removed in any other way. Whereas criminals are usually quite successful in finding ways to spend (or launder) ink-smudged banknotes, this will be impossible with glued or torn banknotes. The cash is completely worthless, because nobody will accept a brick of paper or mere shreds as payment. Nor will they fit into automated payment terminals.
