I am forever amazed that people can read into scripture what is not there in complete disregard to the command not to do just that.
Rev 13:16 And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads:
Rev 13:17 And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name.
Where pray tell me does these verses say anything about a cashless society, or a computer chip implantation. It speaks of a visible mark, period. If it were a invisible mark, most people are already lost for they already do most of their business with an invisible number they carry in their purse or wallet.
