Missing Exceptions: Notably, the law does not explicitly exclude vending machines, parking facilities, live sporting events or rentals of consumer goods, which sets it apart from similar statutes in other jurisdictions.4 Because on-premises internet transactions are covered by the law, the treatment of bill payment and financial services kiosks under the law is ambiguous.
According to this, it's hard to say. Seems as if sporting venues will need to accept cash. I guess MSG forgot to send their lobbyists.
