VeriFone this week launched a new service for NYC taxi passengers, letting customers pay for a cab by tapping any compatible smartphone. Way2ride utilizes Zoosh ultrasound technology, enabling secure payments using the speaker and mic in your device and the payment terminal on the other end. The app, available for Android and iOS devices, lets you pre-select payment info and even a tip amount. To initiate a transaction, you'll simply tap your phone anytime during the ride, then hop out right when you reach your destination -- a receipt will appear within the app. You can even use the app to hail a cab, estimate your fare and report a lost item.
