Mr Paumen has a chip under the skin of his left hand, and it lights up when it comes into close contact with a payment machine
A microchip was first implanted into a human back in 1998, but it is only during the past decade that the technology has been available commercially.
And when it comes to implantable payment chips, British-Polish firm, Walletmor, says that last year it became the first company to offer them for sale.
“The implant can be used to pay for a drink on the beach in Rio, a coffee in New York, a haircut in Paris – or at your local grocery store,” says founder and chief executive Wojtek Paprota. “It can be used wherever contactless payments are accepted.”
Walletmor’s chip, which weighs less than a gram and is little bigger than a grain of rice, is comprised of a tiny microchip and an antenna encased in a biopolymer – a naturally sourced material, similar to plastic.
