The office that microchips its staff

A new office block in Sweden is offering workers the chance to have a microchip implanted under their skin to allow them to access to various services within the building.

A tiny gadget the size of a grain of rice is implanted in employees hands. It then allows them to open doors, or use the photocopier, without a traditional pass card.

Chief technology correspondent Rory Cellan-Jones went to try it out. BBC
