Venmo Touch

Venmo is a well known mobile payment app. They also have a service that makes it easier to checkout in other mobile apps by saving your credit and debit cards and allowing you to re-use them later without having to re-type all of the card details, Venmo Touch. 

We created a video that communicates the need for this service by showing the frustrations of trying to make a mobile purchase. 

update: since this video Apple Pay has come on the scene, but may I ask that you think back before Apple Pay ;)
