"There are 4 billion mobile phones in the world, but only 2 billion bank accounts. That's not just a bit of trivia, but the very raison d'etre for the new mobile payment service called BOKU, launching out of stealth mode today. The service essentially turns your phone into a credit card, allowing you to pay for things "by mobile" with the charges showing up on your cell phone bill at the end of the month." - Alan Cheslow from Bookmarklet
