Cheaper too, and no passport or minimum balance required. Requires nothing but a smart phone, and I hear that's already on most people's wish list even in the driest of all places on earth.
The banks won't solve any of the problems these people have, they are just a pain in the butt. Hong Kong's domestic helpers experience this first-hand, many banks (all?) simply don't want to have them and if they do they charge an arm and a leg.
Just one of many reasons in my opinion why I think a digital currency such as Bitcoin is unstoppable.
I think the KYC rules will be mainly for the modern world and for moving money in and out of Bitcoin. This (moving money in and out) will become less important as time goes by. Just think of how "universal" Facebook is. How long will it take the world to have a universal online currency of some sort? It didn't take Facebook very long and in some countries people use it without realizing they are on the internet (I am still not in Facebook by the way).
Speaking of high risk transactions, the airline industry seems to be happy about moving away from credit cards:
Earlier this month, UATP, a payment network for airlines, announced it was teaming up with Bitnet, a bitcoin processing platform, to offer 260 of the worlds largest carriers the option of accepting the currency for flight bookings. UATP merchants provide 95% of global airline capacity, counting among their ranks mainstream brands such as British Airways, Lufthansa, Delta Air Lines and Southwest Airlines. The company also works with 130,000 travel agencies, plus big rail operators such as Amtrak.
