At first glance ....
At first glance, despite Hipsterman's ridiculous pitch, there are actually a few desirable features being proposed, but I am dubious about the practicality of the whole thing, in terms of implementation and cost. It does integrate several items that I sometimes carry around when I travel. And I did leave my phone on my windscreen again last night (doh).
But my wallet is already thick enough without adding a battery and a bunch of electronics; I just can't see any way that this thing is going to be something I actually want to squeeze into my pocket. And how's that global wi-fi hotspot going to work? Is that just basically an embedded MiFi that you're going to buy a local SIM card for wherever you, or are they talking about something more interesting? And you're now going to add your wallet to the list of things you have to charge up every day?
I will be amazed if this ever actually sees the light of day.
