How microchips inserted under the skin could unlock the future – and the door to your home
Volunteers in Australia 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.
Once the needle is removed the incision heals in a few days and the microchip remains, allowing the wearer to open doors with the brush of a hand – provided they only wish to access one particular place.
Commercially available insertable microchips are only large enough to hold one access code and a small amount of other information, so the days of replacing an entire wallet and keychain with a tiny computer under the skin are not yet upon us.
The future is coming, but it’s not in a rush.
Ten volunteers received a microchip at the Australian Centre for the Moving Image in Melbourne on Tuesday to mark the launch of Pause Fest, a technology and culture festival now in its eighth year.
