Sleepwalking into disaster? Requirements engineering for digital cash

Conference Object
Change log

You all have some cash. Perhaps not on you right now, because payments are increasingly becoming digital—indeed, for me, it’s been a while since I stopped carrying a wallet. But you’re all well familiar with banknotes, obvi- ously. Now, imagine money that, if you didn’t spend it by a certain date, would self-destruct—like the glasses with the secret instructions in the opening credits of Mission Impossible II. And I’m not just metaphorically talking about “self- destructing” in the sense of being eroded by inflation. No, I’m talking about currency that completely disappears if unspent: you can’t spend it any more after a certain date.
