Westby said he and his family will be chipped, too.
The chip, which costs $300 per implant, is inserted with a needle between the thumb and forefinger and "barely hurts at all," he said.
It also takes away the inconvenience of a forgotten employee badge or credit card. Once an employee has the chip installed, he or she can purchase food in the break room, open doors and log into computers.
And for those who may be concerned about Big Brother watching, Westby said there is no way for employees to be tracked.
"Unlike your cell phone that is trackable and traceable pretty much no matter where you are, this device is only readable if you're within six inches of a proximity reader," he said.
He also said the chances of the chip being hacked is "nil to none."
"It is a very secure and safe device."
Three Square Market's partner, BioHax International in Sweden, has already started using the microchips in about 150 of its employees, he noted.
