GLEBE, AUSTRALIA — A new trend has been developing in Australia, with hundreds of them implanting microchips in their hands that allow them to remotely unlock doors. <br /> <br />“You could set up your life so you never have to worry about any password or PINs,” Shanti Korporaal told news.com.au. <br /> <br />Korporaal, from Sydney, set up a business called Chip My Life with her husband. She has two implants in her hands. <br /> <br />The microchip is roughly the size of a grain of rice. There are two types of microchips available for sale: RFID and NFC. <br /> <br />The chips can be used to replace identification badges to unlock secure doors or transfer medical data.
