Most religious scholars truly believe the mark will be little chip implanted under the skin that will house every piece of information about us including what is in our bank accounts. In essence we will be a cashless society and will pretty much have our own "bar code" in our bodies that will be scanned when we buy or sell anything. We will have the choice to have this implanted and if we chose not too, we could be put to death. Today's technology makes this ancient prophecy all the more fascinating, at least to me.
