This comes without the bogus $30/mo Pro membership fee PayPal charges for checkout on your site. I have limited experience with both, but sounds like a score for Amazon to me.

Maybe I've misunderstood PayPal Pro, but ultimately don't customers leave your site for the final checkout with PayPal?

Interesting development. The fees look to be identical to PayPal and Checkout, but calculated on a three month average. There seems to still be room for another competitor here, given the problems with both PayPal and Checkout.

It would be nice if they accepted credit cards without having an Amazon account. Like Paypal Website Payments Pro.

Agree. For software vendors, I think this limits usage as an alternate payment option for B2C products.

Is this flash based or is it an iframe? How are they mitigating the risk of malicious sites that steal a users credentials as they are entered into an observable DOM hierarchy?

Edit: Looks like authentication is entered into a pop-up window, but still I'm not convinced that it's secure.

I imagine it's something similar to the Facebook Graph API. Popup for login, website receives a token to retrieve data. Can anyone verify this?

I like the Windows XP themed popup at second 16: https://payments.amazon.com/sdui/sdui/business/cba/CBAvideo

It shows a Firefox browser with an IE popup. I'm guessing they stitched together screen parts for their video.

somebody's gonna get SUPER RICH implementing a "copy and paste" javascript snippet that allows you to accept payment from paypal, amazon, moneybookers, credit cards, SMS, and whatever else is fashionable in the local region.

Say someone made a site that produced these snippets. How would they become super rich off it?

it solves a problem for pretty much everyone who sells things online. maybe you could charge 1% of transactions or something.

You wouldn't know what transactions occurred, and 1% of a company's revenue is not a reasonable payment for doing nothing but saving time copying-and-pasting implementation scripts from the individual payment sites.

If you meant that this site should somehow provide a payment button for all those providers without even opening an account with them, that's not a problem you can solve with technology. Know-your-customer banking laws and factoring clauses in merchant agreements mean you can never create that service.

Just charge a fixed fee. Why charge a %age? Not necessary. (I know, everyone does it. Doesn't make it right, though.)

That's what my startup is doing - fleapay.com - sort of.
