Actually, there have been a large number of things in this category which have been identified as precursors of the Mark of the Beast. I remember as a child when I was taken to a theme park along with my grandparents and they were mightily upset when they were administered a rubber-stamped admission mark on the back of their hands so that they could enter and exit the park without paying every time they returned. They were convinced that they would lose their salvation by accepting this version of the Mark of the Beast.
In fact, the entire concept of establishing means of identification is a precursor. In the United States all citizens are given Social Security Numbers. When Social Security was established by Franklin Roosevelt many sincere Christians were convinced that this was the precursor of the Mark of the Beast. In addition to SSNs there are driver's licenses, identification cards of all sorts, credit cards, and all forms of censuses. The use of a census goes all the way back into the mists of history. Moses took two of them. David did one. When Jesus was born the Roman government was doing another.
