Your wallet holds a lot more than just the "fun" plastic that lets you buy stuff. It also holds IDs, public transportation passes, concert tickets -- and Google Wallet may soon hold all the same things.
In a Q&A session on YouTube last night, Wallet product lead Robin Dua told viewers that payments are the the most obvious first step for Wallet, and Google hopes to bring a wide range of identification, travel, event, and other credentials into users' virtual, cloud-based pockets.
While not yet applicable to the developing world, this wide range of applications is definitely a step in the right direction in propelling mobile payments via a comprehensive mobile wallet strategy.
