A Wisconsin company is going beyond the company badge. Three Square Market is offering to microchip its employees – so that they can enter rooms and access snacks in the cafeteria without needing pesky things like cash.

The microchip would be inserted on their hand. So far, more than half the company’s employees have signed up, according to reports. (There’s a ring or wristband for those who might not want to embed anything under their skin. No word on what happens if someone decides to quit.)

“It was pretty much 100 percent yes right from the get-go for me,” a software engineer told The New York Times. “I like to jump on the bandwagon with these kind of things early, just to say that I have it.”

The company says the chip cannot track its employees’ movements, but ethicists are concerned other firms may see an easy way to, say, make sure employees are where they say they are or to monitor breaks.

Less voluntary procedures have raised serious health and ethical concerns – such as, in 2005, when a microchip company attempted to chip residents of a Tennessee facility for the developmentally disabled, who couldn’t legally give consent. That company, VeriChip, has proposed implanting chips in legal immigrants and guest workers. 

With privacy concerns being raised for everything from online shopping to Disney trips to Roombas, it’s worth people pausing a moment to decide for themselves how much they are willing to let businesses know about them for the sake of convenience.
