Clemson University is starting a clear-bag policy and a re-entry voucher system at its football games this season.
According to the Associated Press, anyone who wants to take a bag bigger than 4.5 -by-6.5-inches into Memorial Stadium will have to use a clear plastic bag.
Fans who want to leave the stadium and come back in must get a voucher before leaving. Then, in order to get back into the stadium, they must show the voucher with a valid ticket.
The vouchers will be available through the third quarter. Fans will be able to leave during the fourth quarter, but will not be allowed back inside the stadium.
Similar policies are also being used by many college and NFL teams.
