In the 2011 film, “In Time,” starring Justin Timberlake, people have a built-in microchip clock-type device on their arm to top up and spend credits with. The clock is constantly ticking down in real-time, too, just by living, and people are forced to commit crimes to steal time from other humans to survive. Overall, a rather dystopian future is presented, where people are always conscious of their need to earn time just to survive another day. It’s noticeable in this film, too, that extra credits are given out to favoured interests by the overlords running the system and deducted from others. A likely increased future feature of currency issuance, as technological advances continue.
