For Amal Graffstra embedding two microchips into his hand and wrist to enable him to unlock his computer and home with a simple wave was a no-brainer.

Mr Graafstra started "biohacking" over a decade ago, working to embed radio-frequency ID (RFID) and near field communication (NFC) chips into his body.

Interest in his work was so intense he started a business selling implantable human-friendly microchips, not unlike those found in pets.

"Originally I just wanted to get rid of my keys, but now the idea of biohacking is human augmentation in general," he told the ABC.

"These devices are non-medical so they're purely augmentative, they give me capabilities that I didn't have before."

Mr Graafstra is from Seattle and is in Australia for the Deus Ex Mankind Divided Augmented Australia conference.

"The idea of creating devices that are totally possible to create today will enhance human capabilities," he said.

"We want to be able to democratise the technology, make it accessible, make it safe."

Mr Graafstra's company Dangerous Things sells embedding kits that cost between $US50 to $US100, with an additional $US100 to get the device surgically implanted. The company has sold around 15,000 kits, with around 200 kits sold in Australia, the third most popular country for the start-up.

The relatively low entry price to access the technology means those curious are able to buy online and effectively "hack" their own bodies.

It has spanned a movement of people known as "grinders" - those who seek to improve their own bodies with electronic devices and a do-it-yourself ethos.

"I think this is a really interesting time for biohacking and for technology in general, now that we're seeing the number of people interested in human augmentation and extended human capability increasing," said Jonathan Oxer, a Melbourne man, and one of relatively few people in the world who has been surgically implanted with an RFID chip.

"We're going to start seeing a lot more systems being developed that allow us to control things using our mind or connecting devices to our bodies we can control.

"Traditionally that has taken very expensive research projects to bring that sort of thing about.

"A lot of the tools being released now are open source. What that does is allows us to collaborate on the design and in the same way as open source software allows many developers to work together."

While the chips available now enable users to unlock their homes, start their cars and store their ID, Mr Graafstra envisions the future will bear more applications including tap and pay, and monitoring health.

Earlier this year Mr Graafstra created a prototype smart gun, where the trigger could only be activated by the chip embedded in his arm.

"A lot of biohackers are enthusiasts, they also want to see the day where we have a freedom to do what we want with our own bodies, much like tattoos and piercings we're becoming more mainstream," he said.

"The idea of a enhancing your capabilities with implants is going to be normal," he said.
