I was actually reading this story earlier today. There was a later minor retraction of sorts indicating that the Amazon payment system had been in effect for a while. It was the new system roll out for recurring payments, like monthly bills.
Either way, I agree. Amazon will be a major factor in this.
By the way, what ever happened to the Visa system, V.me?
Just goes to show you that Amazon is THE master (er, .guru) of advertising and promo.
