Customers who want to pay with a $100 bill at a Rhode Island chain of restaurants will now have to fill out a form.

WJAR-TV reports that all four locations of Gregg’s will now require a name, phone number and driver’s license number whenever someone pays with a $100 bill.

Owner Bob Bacon says it’s because they have received five fake $100s in the last three months. He tells the station the policy is not about getting restitution if they receive a fake bill. He says it’s about creating a paper trail so they can track down whoever is making the fake bills.
