Dozens of employees at a Wisconsin technology business were implanted with microchips Tuesday at the company’s headquarters.

Three Square Market, also known as 32M, said 41 of its 85 employees agreed to be voluntarily microchipped during a “chip party.” The chip, about the size of a grain of rice, was implanted into each person’s hand using a syringe.

Company officials said the implants were for convenience. The radio frequency identification chip provides a way for staffers to open doors, log into computers, unlock things and and perform other actions without using company badges or corporate log-ons.

The chip is not a tracker, nor does it have Global Positioning System capability in it, so the boss can’t track worker movements, company officials said.

Three Square Market said it was the first company in the United States to offer staff the technology similar to that used in contactless credit cards and in  chips used to identify pets.

The implants, made by Sweden’s BioHax International, are part of a long-term test aimed to see whether the radio frequency identification chips could have broader commercial applications.
