A ticket inspector who scanned a New South Wales travel card chip implanted in a man’s hand said “Wow, that’s crazy” when her reader pinged to confirm he had tapped on before boarding the train.

But that wasn’t enough to save Meow-Ludo Disco Gamma Meow-Meow who, on Friday, pleaded guilty to fare evasion because he could not produce the Opal card when confronted by the inspector.

Bodyhacking scientist Meow-Meow – his legal name – pleaded guilty in Newtown local court to attempting to travel without a ticket and not showing a ticket for inspection in August 2017.

The penalties were issued by Sydney Trains despite Meow-Meow’s hand implant returning a “valid tap-on” to the inspector’s Opal reader.

The 34-year-old was convicted, fined $220 and ordered to pay costs of $1,000 for attempting to travel without a ticket. No conviction was recorded for his failure to produce a valid ticket.

Court documents show Meow-Meow’s Opal card was tapped on during his journey through Stanmore and had a credit balance of $14.07.

He had cut down his Opal card chip, had it encased in biocompatible plastic and then implanted it just under the skin on his left hand by a piercing expert in April 2017.

The operation, which made headlines around the world, was swiftly followed by a Transport for NSW threat to cancel cards that had been tampered with.

It took less than a day for Meow-Meow’s registered card to be cancelled but, because the chip under his skin was not linked to his name, it remained active until February when it, too, was cancelled.

Meow-Meow on Friday said he was disappointed to be fined and was exploring other options that would allow him to use an implanted chip to pay for his train travel.

“New technology can be scary if you don’t understand it,” Meow-Meow told reporters. “People have been scared of lots of technologies when they come along.

“[But] this is the next evolution from going from paper tickets to Opal cards to something which means we don’t have to actually carry anything at all.”
