A Sydney biohacker has come up with a way of getting home even if he loses his wallet - and all it involves is a simple wave of the hand.

But be warned this isn't for everyone as Meow-Ludo Disco Gamma Meow-Meow, which is his legal name, had his Opal card implanted underneath his skin.

That means rather than rummaging through his wallet or bag and tapping the travel card against the machine, he waves his hand over the scanner.

Mr Meow-Meow had the 10mm by 6mm chip inserted under the skin of his hand and said it meant he always had the card on him, the ABC reported.

"It gives me an ability that not everyone else has, so if someone stole my wallet I could still get home," he said.

Mr Meow-Meow had the small chip encased in bio-compatible plastic which was inserted on his left hand.

He told the ABC he can even top up his "card" using his smartphone.

While it may sound convenient he admitted it does have a downside which includes having to be just a centimetre from the reader.

Mr Meow-Meow, who had his chip implanted by a piercing expert, said the decision to do what he has shouldn't be taken lightly and can lead to infection if not done correctly.

And he admitted there was another issue at hand — as his actions breached Opal's terms of service, which prohibit tampering.

"It will be really interesting to see what happens when the first transit officer scans my arm," he said.
