Lumen Field only accepts cards (no cash or check) for concessions, retail, parking, and vendors/hawkers in order to provide a faster, more efficient sales process. Fans with cash who do not have a valid credit or debit card can insert their cash into the self-service kiosk and get a prepaid card back. There are 10 cash-to-card kiosks around the stadium and event center. You can load any amount of money from $1 up to $500 per card and there is no transaction fee. The cards can be used inside or outside the stadium; so, if you have money left after an event, take the card with you and use it everywhere major cards are accepted.
