Personally I don't care about cybernetic implants, and I hate conspiracy theories with a passion. I think it's a bad parady of what the Bible is actually saying. Consider that it speaks of a mark on the hand or forehead, needed to buy or sell, and that this is from a vision of the apostle John in his latter days.
The mark is symbolic, it represents our actions and thoughts like the Tefillin
>Deuteronomy 6:8
>Exodus 13:16
I think that the mark represents any way that Satan forces people to sin in order to exchange currency, such as lewd advertising, prostitution, bribes, using God's name in vain (In God We Trust), cheating, lies, pride, usury, debauchery, etc.
There will come a day when buying bread will become impossible without sinning,
>Revelation 13:17
"so that they could not buy or sell unless they had the mark"
Guard your hearts at all times, do not borrow above what you are able to repay, and avoid temptation.
