This is a quick video to go along with our article in UX Magazine: http://uxm.ag/ct
We (http://boltpeters.com) conducted an observation of 14 customers over three months at our neighborhood coffee shop, Sightglass, who just happen to be early users of http://squareup.com on both the iPhone and the iPad. We observed and recorded those customers’ mobile payment interactions with the Square app, and interviewed select customers. Our first study was in December 2009 with the iPhone, and then a follow-up in April 2010 with the iPad.
We did all this to compare the real-world usage in a business context of the iPad vs the iPhone. To get the latest follow us here http://twitter.com/boltpeters
