Also, tokens can be used by an arcade as a form of coupon. Buy [some food item] and get 2 tokens. Kids: bring in a report card and get a token for every A. And many more ideas.
I think the biggest item for arcade operators is centralizing where all the real cash is. At the close of business each day, just take the cash from the change machines. You only go around to the cashboxes of individual games when you need more tokens.
Salespeople for the token manufacturers will be happy to tell you about other creative uses, and will also give you advice about acceptors and all the other aspects of coin-handling that may be different with tokens.
