A Wisconsin company called Three Square Market is going to offer employees implantable chips to open doors, buy snacks, log in to computers, and use office equipment like copy machines. Participating employees will have the chips, which use near field communication (NFC) technology, implanted between their thumb and forefinger. It's an extension of the long-running implantable RFID chip business, based on a partnership with Swedish company Biohax International. The vending kiosk company, also known as 32M, will "chip" employees at a party on August 1st. (According to an email to The Verge, chips and salsa will be served as snacks.) Around 50 people are supposedly getting the optional implants.

NFC chips are already used in a couple of workplaces in Europe; The Los Angeles Timesreported on startup workspace Epicenter's chip program earlier this year. In the US, installing them is also a form of simple biohacking. They're essentially an extension of the chips you'd find in contactless smart cards or microchipped pets: passive devices that store very small amounts of information.
