Food trucks are not a big business. If you've captured the entire food truck payment system, you're still not likely to be worth $6bn, especially not if you're taking pennies on each transaction. It probably also doesn't take so much money to manage such a business. I know someone who works at Square and it's your typical high flying startup wasting money on pretty offices, amenities, and other non-business related expenses, all while losing $100m a year with nary an idea for how to ever reach $6bn in valuation. The people giving out this money to Square aren't stupid, so there's probably something we don't know, but then again the same kind of people gave a lot of money to Color, RockMelt, Quora, Foursquare and some other less memorable walking zombies.

Square's value is that it reduces the overhead for economic participation. If you believe that in the future there will be a more networked economy with a larger number of small businesses and individual tradespeople, then Square is a great bet.
