Dr. Carl Sanders helped design the 666 microchip.

Dr. Carl Sanders was an engineer for over 30 years. He was not a
Christian when helping create the microchip. It was determined
with his research team that was made up of 100 people from General Electric, Motorola, Bell laboratories, Boston Medical Center and Stanford University that the forehead and hand were ideal to put the microchip in because it provided the necessary temperature change for current to flow to be able to recharge the battery.

Revelation 13:16-18
King James Version
16 And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads:
17 And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name.
18 Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and his number is Six hundred threescore and six.
