iButton becomes your personalized token and acts like a small change purse for one or multiple applications. Your iButton enables you to complete transactions, like dispensing a candy bar or metering a prepaid volume of water. iButtons eliminate the need to carry small amounts of cash, and a single iButton can service multiple, independent applications. They are perfect for a wide variety of eCash functions like mass transit systems, parking meters, gaming systems, vending and fleet refueling.
