“Let the one who has understanding calculate the number of the beast, for it is the number of a man, and his number is 666” (Revelation 13:18).
This verse from the Revelation of Jesus Christ describes what is known as “the mark of the beast,” and it is no longer science fiction. BAR codes are commonly used in retail operations to make purchases. Through advanced technology, it is now possible to place a small chip the size of a grain beneath human skin and store all kinds of information.
During a time in future Bible prophecy known as the tribulation, the Antichrist and the false prophet will use codes containing the number 666 to track humans and control the world economy.
