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.

“You could set up your life so you never have to worry about any password or PINs,” Shanti Korporaal told news.com.au.

Korporaal, from Sydney, set up a business called Chip My Life with her husband. She has two implants in her hands.

The microchip is roughly the size of a grain of rice. There are two types of microchips available for sale: RFID and NFC.

The chips can be used to replace identification badges to unlock secure doors or transfer medical data.
