I don't understand the question because that's all referring to things that existed in the 1st century that no longer exist today. What the Mark of the Beast specifically is referring is the common practice at the time to brand your forehead to mark yourself as property of the god you worshiped, as well as the stamped (the word,
xáragma means stamped or engraving) image of the emperor's head on every coin of the Roman Empire, without it nobody could buy or sell. The very coinage of this image showed conveyed the emperor's claims to divinity, showing the emperor in the sun's rays, as well as being symbolic of the all-embracing economic power of Rome. It was either in their hand or in their minds (the head), and there is even evidence of business transactions being proceeded by pagan formulas and practices. Due to all of that, it became increasing difficult to impossible for Christians at that time to function in such a world that promoted idolatry to that degree.
We know that the Roman Emperor, and more specifically Nero is the beast using numerology, remember it says to calculate the number. 666 (or 616 in some manuscripts) is a code called gematria (Hebrew) or isopsephy (Greek), where each letter corresponds to a number. When in scripture it says "Let the person who has insight
calculate the number of the beast, for it is the number of a man. That number is 666.", it's literally asking the readers to decode who's name equals 666. The person who John is referring to by this code is the Roman Emperor Nero, who's name is Greek is "Nerōn Kaisar", which in Hebrew would be נרון קסר. In Hebrew gematria, Resh (ר) is 200, Samech (ס) is 60, Qof (ק) is 100, Nun (נ) is 50, Vav (ו) is 6, then you have Resh (ר) again and Nun (נ) again; add all of those up is 200+60+100+50+6+200+50, which equals 666. The 616 found in some manuscripts comes from the Latin for Nero "Nerō Caesar", or נרו קסר in Hebrew. The spelling for that is Resh (ר) for 200, Samech (ס) for 60, Qof (ק) for 100, Nun (נ) Vav (ו) for 6, then you have Resh (ר) again, but only Nun (נ) for 50; so if you add that up its 200+60+100+6+200+50, which equals 616. Plus, if you break down the characteristics of the beast in a symbolic nature of what is occurring when John wrote it, it matches up identically to Nero, which is almost blatantly explained in Rev 17 "The seven heads are seven hills (Rome was known as the city of Seven Hills) on which the woman sits. They are also seven kings. Five have fallen (The first five Roman Emperors), one is (Nero, the sixth Roman Emperor), the other has not yet come; but when he does come, he must remain for only a little while (Galba, successor of Nero who only had a short reign of seven months). The Beast speaks blaspemies against God (Nero was arguably the biggest on emperor worship and inscriptions in other places have referred to him as "Almighty God"), he makes war against the Saints (Nero was also the biggest and first to widely persecute Christian, and did so for 42 months, which is what
Revelation 13:5 says), he kills himself with a sword as referenced in verse 10, and the reference to it being later healed in 13 & 14 is in reference to the Nero revival myth.
