There's not much can surprise me in when it comes to staff monitoring, but I was shocked to read that Swedish bio-hacking group BioNyfiken has implanted staff working at a new high-tech office complex in Stockholm with microchips.

According to the BBC, in time, all of the 700 staff who will work for businesses at the new offices will be able to use the chips – similar to those in contactless payment or travel cards – to enter the building, use the photocopier and pay for their lunch rather than using traditional swipe cards.
