People On the Street Cashless Pay

Over the recent years, cash has somewhat escaped from peoples wallet in exchange for credit/debit cards, apple/google pay, and venmo. These digital methods of payment have been popular amongst the majority of the population. As a big time sporting event goer, I have recently seen that stadiums and arena now have stands and shops where you are no longer allowed to pay with cash. Instead you must use a card or your phone. It seems as if major sporting venues are trying to eliminate cash from their stands and shops.
