Whenever you go out to dinner or any other event with friends, there may the usual drama...splitting the bill. So why not make payments by tapping two phones? App developer Bump has just launched Bump Pay, an application that allows you to pay your friends just by tapping you iPhones! The app is very simple to use, first, the user enters the value you want to transfer to another person, that done, just touch the two phones (both must have the app) so that your debt is paid. Bump Pay is available only for iOS with PayPal as the payment system, but the company is already thinking about adding other payment methods to the application.
