Paper, not plastic, is still the currency at many fairs across the state.
But after decades of dishing out dollar bills, credit card readers are starting to become more common.
At the Vilas County Fair in Eagle River, it's still all about the green. For most vendors, cash is the only option.
"Old school, oh yes, old school, just bring that pocket book and have a good time," said Edie Kukanich, fair board treasurer.
Paying with paper is a sort of tradition at fairs.
"I like cash. Cash is good," said Donald Oxendorf of Alvin.
Those working food booths say cash is faster.
"Time wise, we're quite busy so taking credit cards just takes that much longer so taking cash is just that mush easier," said Vicki Mendham, a concession stand volunteer.
But for fairgoers, switching from swiping cards back to dollar bills is an adjustment.
"I would have to plan ahead of time to go to my bank and get a large amount of cash to bring and then I'm afraid I'm going to lose it and then I never know where each dollar goes," said a fairgoers from Merton.
Fair organizers say they made an ATM available for those who forgot cash or ran out while they are are at the fair.
There are a few stands that will take a card.
"Normally we get a lot of people that are really excited about it, they're like 'Finally, someone takes credit cards,'" said Eleni Fletcher, a manager at Fletcher Concessions.
Fletcher has been traveling with fairs her entire life. She says the business might finally be changing.
"It's something that is catching on more at the big fairs but at the little fairs not so much, yet," said Fletcher.
When that transition from cash to credit transaction happens, it'll be a relief for many fairgoers.
But for now, cash is still king.
"Out there they all want cash," said Kukanich.
The Vilas County Fair continues through the Sunday.
