People are using chip implants to open doors, control phones

Chip implants are becoming increasingly popular among so-called biohackers to control phones and perform other technological tasks.

Now playing: Watch this: Man implants NFC chip to control his phone

Minnesota software engineer Tim Shank uses a chip implanted in his finger to unlock the smart lock to his home. He also has an NFC chip with contact information stored in it, which lets him easily tap and send the info to an Android phone.

Rather than heading to the doctor or nurse's office to get the implant injected, the procedure is commonly being done by tattoo shops and piercing parlors. The chips, alongside an injection kit, sell for $57 online.

Shank is just one of a growing movement of biohackers who are implanting devices and chips in their bodies to perform different technological tasks.

In 2015, an Australian artist implanted an ear in his arm with a built-in microphone. The intention was to connect the ear to the internet so anyone could hear what he was hearing.
