The mark will be that proverbial line being drawn in the sand in that, all other methods of buying and selling will be made obsolete during the beasts reign so that only the mark will be a valid option for electronic crediting and debiting, which will force people to make a decision to receive the mark or reject it. Unfortunately, many will receive it because it will be the only way to pay for anything. This is the meaning of the scripture which says "He forces all both great and small, rich and poor, free and slave to receive a mark in the hand or the forehead and except anyone had the mark they would not be able to buy or sell." The forcing will not be by physical force, but by making all other methods of buying and selling invalid, leaving only that mark as a means of electronically crediting and debiting ones bank account.
Consequently, anyone who receives the mark will be aligning themselves with the beast providing undeniable identification, like a symbol giving irrefutable connection between parties, which is what the word "Charagma" translate "mark" means. This mark will not only affect communism, but the entire world.
