"You have to keep changing and adapting or you're going to have a 'closed' sign on your door," owner Marc Tanjeloff said. "I remember at one point we were writing checks and using American Express sliders. It's just the future, it's changing."

There's no single person or organization in charge, so instead of banks processing the transactions, computers do the work for you.
