The End of Money is out in paperback! To celebrate, I've been checking in with some of my favorite characters populating my curious missive about moola. Here's Dave Birch:

"If there's one thing that has changed in the world of cash replacement since David first interviewed me for the book, I'd say it was the spread of identification and authentication technologies. If you know who the counter-parties to a transaction are, the payments part is easy. Identity is the new money, as they say. Or, at least, as I say. Now that the mobile phone has created a new platform for identification and authentication, the need for cash for interpersonal transactions has further receded."
