PayRange has been awesome and the adapt rate has been huge! People just don't carry cash anymore like they used to. PayRange is safe and secure. The operator and PayRange don't ever see your card number. Only the bank processor. In fact the operator doesn't even know who is making purchases. I only see a transaction number when a game is credited using PayRange.
That said, I would really like to have machines call home and notify me of issues so I can make better use of my time when on location working on games.
