i would like to see more payrange like systems, maybe even google pay so its cheap or free for the operator. in asian countries most payments are digital. its more secure, trackable, and you can do things like remotely adjust pricing on the fly (happy hour), and there are no coin mechs to jam. heck at some point id like to see pinballs have diagnostics that can be sent to an operator, and if a ball goes missing the operator can send a digital refund.
