When fans return to watch games at Allegiant Stadium in Vegas, they can leave their cash at home.
The new Raiders stadium is set to be the first professional sports venue in the U.S. to go cashless.
If you want a hot dog and beer at halftime, you'll have to pay with a debit card, credit card, or something like Apple Pay.
If you forget, there will be kiosks set up in the stadium where you can exchange cash for a prepaid card to use.
