to do this, you would need to pray that amazon doesnt sue you for violating their one-click checkout patent, and given that they have their own payment system, i cant imagine it is very likely this would go uncontested. further, if you removed the "one-click" aspect of it, i dont really see how this is any different than paypal on a meaningful level. paypal doesnt treat merchants well, but for customers they are quite good and the process is really simple and takes only a few clicks. i have to think that if it werent for amazon's patent, they would have a one-click checkout button. this seems like the author took an idea that was already implemented and dreamed of ways that it could be better without thinking of feasibility (e.g. assuming that the cc companies would exempt themselves from their fees so that micropayments become feasible)
