Dozens of employees at this Wisconsin vending company lined up to have a microchip implanted in their hand.
The chip, which is about the size of a grain of rice, allows workers to log in to computers, use the copy machine or buy snacks by simply putting their hand up to a scanner.
The microchip is FDA-approved and is injected between the thumb and index finger using a syringe-like instrument.
(SOUNDBITE) TONY DANNA, THREE SQUARE MARKET SAYING:
"I thought it went great. You don't know how it's going to feel or what it's going to feel like. In my opinion, it really didn't feel like anything."
The company says it's the first in the U.S. to offer this type of technology, part of a long-term test to see if microchips can have broader commercial applications.
(SOUNDBITE) TODD WESTBY, THREE SQUARE MARKET CEO, SAYING:
"Imagine being able to travel without a passport or worry about losing it. You just hold your hand up and all the documentation comes up."
Westby says the microchips are not GPS enabled and will not be used to track employees.
But critics argue the technology raises red flags about privacy.
