The mark is about worship and keeping the commandments of God (Revelation 14:11-12).
I believe it will likely be specifically to do with the Sabbath; “… they have no rest, day or night, these worshipers of the beast and its image, and whoever receives the mark of its name” (Revelation 14:11). The Sabbath is the only commandment that contains God’s name (YHWH or YHVH/YHUH), title (Elohim), and dominion (heaven and earth, the sea, and all that is in them), making it a seal of sorts. This concept of the Sabbath acting as a seal is often tied to the idea that God's Law, particularly the Ten Commandments, reflects His character and authority. Thus, the Sabbath functions as a sign of God's covenant with His people, symbolizing not only rest but also allegiance to His rule as Creator. See further reasoning below.
When asked which is the great commandment in the Law, Jesus Christ answered,
“You shall love the Lord your God with all your heart and with all your soul and with all your mind. This is the great and first commandment.
And a second is like it: You shall love your neighbour as yourself.
On these two commandments depend all the Law and the Prophets” (Matthew 22:36-40), at the heart of which lie the Ten Commandments (Exodus 20:1-17) that were written on tablets of stone by the finger of God on Mount Sinai.
The Ten Commandments constitute the basic moral code for humanity, as magnified and revealed in their full meaning by Jesus, and are obeyed to demonstrate the believer’s love for God and their fellow man. Jesus affirmed the enduring nature of God’s Law, declaring that He did not come to abolish it but to fulfil it, and that not even the smallest part of the Law will pass away until heaven and earth pass away (Matthew 5:17-48). Sadly, many who identify as Christians today do not keep the Ten Commandments, especially the second commandment, which forbids idolatry, and the fourth commandment, to remember the seventh day Sabbath, and often teach others to disregard them as well. This is despite Jesus’ warning that those who break even the least of God’s commandments and teach others to do the same will be called least in the kingdom of heaven (Matthew 5:19).
3 And hereby we do know that we know him, if we keep his commandments.
4 He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him.
5 But whoso keepeth his word, in him verily is the love of God perfected: hereby know we that we are in him.
6 He that saith he abideth in him ought himself also so to walk, even as he walked.
(1 John 2:3-6)
If ye love me, keep my commandments.
(John 14:15)
9 And the third angel followed them, saying with a loud voice, If any man worship the beast and his image, and receive his mark in his forehead, or in his hand,
10 the same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation; and he shall be tormented with fire and brimstone in the presence of the holy angels, and in the presence of the Lamb:
11 and the smoke of their torment ascendeth up for ever and ever: and they have no rest day nor night, who worship the beast and his image, and whosoever receiveth the mark of his name.
12 Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus.
(Revelation 14:9-12)
3 For this is the love of God, that we keep His commandments; and His commandments are not burdensome.
(1 John 5:3)
21 He that hath my commandments, and keepeth them, he it is that loveth me: and he that loveth me shall be loved of my Father, and I will love him, and will manifest myself to him.
(John 14:21)
10 If ye keep my commandments, ye shall abide in my love; even as I have kept my Father's commandments, and abide in his love.
(John 15:10)
19 Circumcision is nothing, and uncircumcision is nothing, but the keeping of the commandments of God.
(1 Corinthians 7:19)
24 And he that keepeth his commandments dwelleth in him, and he in him. And hereby we know that he abideth in us, by the Spirit which he hath given us.
(1 John 3:24)
17 And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ.
(Revelation 12:17)
14 Blessed are they that do his commandments, that they may have right to the tree of life, and may enter in through the gates into the city.
(Revelation 22:14)

While I agree with you, I'm also wondering if the biodigital convergence plays a part in the demonic subjugation.
