Summary: Cherian Abraham Principal Analyst - Mobile Commerce & Mobile Payments -- used a 900 mile vacation roadtrip in the US to put the Google Wallet he installed on his new Samsung Galaxy Nexus to the test. He found that contactless payment with Google Wallet and MasterCard PayPass does work and that it can even be fun. Yet, mobile payments require serious improvements, notably: value added services such as geolocalized couponing and seamless communication through the payment ecosystem.
My comment: This blog post has been widely quoted, notably by ReadWriteWeb which was then curated by Trap.it (a competitor of Scoop.it). Better go to the source and read from the expert himself.
