I think things will pretty much be the same with some window differences along the way, until things really change with the coming mark people will be required to have in their forehead or right hand in order to buy or sell.
But don't take that mark, or you will forever be lost with no hope of salvation. (see Revelation 14)
The Book of Revelation is a book of symbols, not a book to be taken literally. The Greek word
esēmanen in Rev 1:2 is literally "signify."

Signify means to indicate or to show by a conventional token, "such as a word, signal or gesture," (Merriam Webster) (and "token" was the original French word that became the English word signify), and the first definition is "to be a sign of: Mean."
In other words, the things the angel shows to John are signs of something, and they "mean" something. You can see this in chapter 1 where John is shown several things and then the meaning of them is provided right there in the text, no guessing involved. This sets up the rest of the book even though the meanings are no longer translated as you continue to read John's visions.
By the time you get all the way to Chapter 14, you ought to be well aware of this. You already read about the two beasts presented in Chapter 13 (pagan Rome and Roman Catholicism), so if you are relating your "mark of the beast" to something other than at least one of those two beasts (and very unlikely to be pagan Rome these days, don't you think?), then you have missed the whole message God was conveying through the visions the angel presented to John, and which John dutifully wrote down as instructed. "Write what you see in a book and send it to the seven churches, to Ephesus and to Smyrna and to Pergamum and to Thyatira and to Sardis and to Philadelphia and to Laodicea." Rev. 1:11.
These things were written to a particular audience, and it was expected that this audience would understand what was written. Indeed, the whole book of Revelation is a message of hope to the christians in those seven churches. The mark is not something literal on hands and foreheads, and it is not something to come in the future, at least not from our vantage point reading about it in 2021.
