A Sydney man has found an ingenious way of never missing his train again by implanting the chip from his Opal card into his hand.
Self-described bio-hacker Meow-Ludo Disco Gamma Meow-Meow (yes, that's his legal name) paid US laboratory Dangerous Things to develop the technology which he can top up with his smartphone, according to ABC News.
"It gives me an ability that not everyone else has, so if someone stole my wallet I could still get home," he said.
And like any regular commuter, he's able to "swipe" using the bio-compatible plastic that's placed the Opal near-field communication (NFC) chip under his skin, measuring one millimetre by six millimetres.
While Meow-Ludo has breached Opal's terms of service by tampering with his travel card, he also cautions against trying a do-it-yourself job at making a similar implant.
"Most certainly don't try this at home unless you know what you're doing," he said.
He added: "Be aware of the risks involved and make a wise judgement based on that."
Meow-Ludo said he had two more implants in his hand and arm, and predicted that NFC devices could become the norm in the future.
"If I could go to a government department and swipe my hand, that would make accessing these services a lot easier."
