Chip ahoy! No more lost keys and cards

Early one morning in 2012, engineer Daniel de Kock was locked out of his office building in Johannesburg because he did not have his access card.That's when he decided it was time for him and his friend Jarryd Bekker to make their idea of implanting access microchips into their bodies a reality.Now these tech wizards simply swipe their hands across a sensor to get into The Diz building, near the University of the Witwatersrand.
