SmartPass is an account that allows you to make contactless payments for items using a SmartPass Tag or Companion Card. With Vodafone SmartPass, you can pay for anything under £20 with your smartphone. Whether it’s for a quick coffee or a bite to eat with friends, there’s no need to rummage around for cash or cards - or borrow money if you’ve forgotten your wallet. Simply tap your phone anywhere you see the contactless symbol and away you go. Plus, you can check your balance or instantly add cash, wherever you are.
While Android version of the app uses embedded NFC module, the iOS app is designed to work with special sticker that allows to seamlessly pay with your phone. I was one of the developers responsible for implementing the application.
