On Friday it was announced that the Rays Tropicana Field in Tampa will become the first stadium in North America to become a cash-free venue. Via the Tampa Bay Times: "Payment forms to be accepted at Tropicana Field this season include major credit cards, Rays gift cards, mobile payments such as Apple Pay and Samsung Pay and season-ticket holder Rays Cards, the team announced in a press release."
Fans in attendance who do not have electronic forms of payment at their disposal will be able to exchange cash for gift cards in $10 and $20 increments.
