A man who has an Opal card implanted in his hand has been fined for not having a valid ticket but is refusing to pay up.
The scientist, who calls himself Meow Ludo Disco Gamma Meow Meow, has been swiping on and off for months using an implanted chip from an Opal card.
Everytime he beeps through the turnstile, Meow Ludo defies authority in the name of technology.
Now, his rogue ways have landed him in court.
"I'm flabbergasted, I think it's ridiculous," he said.
"The fact they want to shut down the most innovative thing to happen in public transport in Sydney."
He was issued a $200 fine for not having a valid ticket but Meow won't pay, and has pleaded not guilty.
"I think that it's actually about bodily autonomy and sovereignty over technology you own, especially when it's implanted," he said.
Transport for NSW maintains it doesn't support Opal cards being tampered with or damaged and customers who do so may have their card cancelled.
But, for now, Meow's implanted one still works.
Meow's court case has been adjourned until March 2018.
In the meantime, he has other pressing matters to attend to.
He's standing as a candidate in the upcoming New England by-election, up against Barnaby Joyce.
