Under the skin: how insertable microchips could unlock the future

Volunteers in Melbourne have had microchips inserted for three months, designed to unlock doors and carry out other tasks. Will they really be any use?

The microchip is about the size of a grain of rice and usually inserted in the webbing between the thumb and forefinger using a needle the same thickness as used in body piercing.

It feels, says insertable technology expert Kayla Heffernan, like getting a drip.
