Three Square Market is to become the first US company to microchip its employees.

The Wisconsin company is offering to implant the tiny radio-frequency identification (RFID) chip into workers’ hands for free – and says everyone will soon be doing it.

The rice grain-sized $300 chip will allow them to open doors, log in to computers and even purchase food.

So far, 50 employees have signed up for the chance to become half-human, half-walking credit card.

Three Square Market, which provides self-service “micro markets” to businesses around the world, was inspired by the micro-chipping already taking place in Sweden, where so-called “bio-hackers” have been inserting the tiny devices into willing participants for at least three years.

Three Square Market are even working with a Swedish company, BioHax, to deliver the new technology, which they see as one day being simply another payment and identification method – only instead of a credit card or phone, there would be a microchip between your thumb and finger.

While a large proportion of the world might think twice before putting a tiny chip in their hand, it seems those at Three Square Market had no such worries.

The chip will replace everything you might have in your wallet – from your key fob to your credit card and ID. For now, it is just aiming to make life easier for those using Three Square Market’s facilities.
