From a primary word στίζω stizō (to “stick”, that is, prick); a mark incised or punched (for recognition of ownership), that is, (figuratively) scar of service: - mark.
The mark will be a device that is put under the skin for the definition is to stick, prick, which can be a hypodermic needle that puts the mark in the person, and a mark incised or punched which is referring it to be put in something which is under the skin for the mark is given to people.
The mark of the beast has to do with technology for the beast's agenda is there is no personal God to help mankind, and benefit them, but mankind's technology and devices can help to achieve peace on earth.
Which will be a microchip just under the skin linked to satellite with all information about the person on the chip including finances for no person can buy or sell without the mark, and to cut down on crime for if a crime happens they will know who was in the location and how close they were to the crime scene, and can locate lost people or whoever they want to locate.
Going along with the beast's agenda and worshipping the beast precedes taking the mark of the beast, and when they take the mark then repentance and salvation are no longer available to the world, and God can end sin on earth.
The New Age Christ, beast, will be of the occult, and the occult believes in the power of numbers for they are about the power of nature, and the adding, timing, and grouping of numbers which they believe will give them more power through nature.
The number 6 is the number of a man, or the soul of a man, so the New Age Christ assigned himself the number 666, a triple 6, for he believes it will give him more power through nature to evolve to be greater and spiritual, and to establish his kingdom.
The New Age Christ will work in the world for three and one half years and push the agenda of the new age movement to condition the world to accept him when he claims to be God.
What will probably happen is that they will eventually not allow people to enter store, businesses, work, and other places people go without a vaccination card to prove they were vaccinated.
But a vaccination card can be lost and then the vaccinated cannot provide for their needs, and the card can be falsified which then then the unvaccinated can be among the vaccinated.
So they will probably go to a microchip under the skin that can be scanned to identify all people who have been vaccinated and want it to be a motivating factor for the unvaccinated to get vaccinated and the chip so they can supply their needs.
