Daniel and Matthew 24 have no mention of this mark of the beast, which is odd because of how important it is. They mention the abomination of desolation, which is not mentioned in Revelations. As we look, we will find they are not the same thing; they are more like different sides of the same coin. They go hand in hand.

Let's have a closer look at the word in Revelations about this mark.

Rev 13:16/17, Also, it causes all, both small and great, both rich and poor, both free and slave, to be marked on the right hand or the forehead, so that no one can buy or sell unless he has the mark, that is, the name of the beast or the number of its name.
Rev 13:18, This calls for wisdom: 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.
Rev 14:9/10 If anyone worships the beast and its image and receives a mark on his forehead or on his hand, he will also drink the wine of God’s wrath, poured full strength into the cup of his anger,
Rev 14:11 And the smoke of their torment goes up forever and ever, and they have no rest, day or night, these worshippers of the beast and its image, and whoever receives the mark of its name.
Rev16:2 So the first angel went and poured out his bowl on the earth, and harmful and painful sores came upon the people who bore the mark of the beast and worshipped its image.

Rev 13:16/17
The first thing to see is that “It causes all” The word “it” (a thing) is used and not he (a person). Some versions, like King James, say “he”. ‘He’ would mean this is done by the Antichrist. “It” means this is done by the Beast from the Earth; are they one and the same? The image and beast that is worshipped is the Forth Beast, which is caused by the Beast from the Earth, or Antichrist. Everyone is to be marked; maybe only the most inner of the circles will remain free from the mark, but I doubt it. The man making this law will be the False Prophet or a political figure.

Rev 13:18
The mark can be both alphabetical (“the name of the beast”) or numerical (“the number of his name”). It is the number of a man. That could mean a particular person, and the one most often accused is the Pope. More likely is that it is the number of a man in the sense of all mankind. It is our biometric number that comes from our cells, which they can read these days. 666 is the number of carbon atoms that we are made from. 6 neutrons, 6 protons, and 6 electrons. The number of a carbon man is 666. The mark that people will receive is not the number or name in its own right, but rather a kind of aerial so your number can be read. We will get on to that. Putting this in place is not something that would be declared; it would just happen. It would take years, and therefore, everything must be in place before the last step of the outer mark. You will have already received the number before we see the outer mark that we would declare as the event in Revelations. All the things done to you will place you in dreadful peril, but taking that last mark is the act that will cost you your salvation.

C Rev14:9-10

We are now in Revelation 14, with the cry of the 144,000. They start off with Fear God, for judgement is at hand, the cry that started nearly seventy years ago. What is this, and how do we see it work out in real life? It is imagined that these are some super-holy saints going around with powerful ministries and performing miracles. As we get closer to the end, we see that this has not happened. What we have seen is a lot of ministries, most overtly Christian, and others you would not know as Christian. Not until you listen to them will you hear from them that they are Christians. What they preach is not straightforward Christianity. They say things like The last days are upon us, beware of the corporate media, as they have an agenda to deceive. Beware; danger is everywhere. We are losing our sovereignty. Since the fall of Babylon the Great in 2020, do not take the mark of the beast. This started with the likes of Herbert W. Armstrong and Hal Lynsay. I have listened to sermons from that era, and they, in general, were aware that things were heating up and times were changing. I enjoyed a sermon from Billy Graham titled “The Writing on the Wall”. However, the cry ‘Fear God’ for judgement is at hand, and it still only came from a few places. It has grown in noise, and these days the likes of Rick Wiles from Tru News and Shaun from the STG Report, Dave from x22, Greg Hunter's Watchdog USA, Maria Zeee, and many more still call out. After the fall of Babylon, that changed to do not take the mark of the beast. Strictly speaking, it says that if you take the mark of the beast, you will receive God's wrath. It may be a description of what it is like in the Lake of Fire, but that represents salvation lost. 

E Rev16

This is the start of the wrath being poured out in full force. We will cover the vaccine in the next section, but it is already being shown to make the vaccinated skin photosensitive. The luciferase in the vaccine is made from an iridescent substance from the firefly. It is very sensitive to light and will glow. The idea is that they can then read that and give it a numerical value. We can truly see Revelation unfold before our eyes.
