International support will come over time. However Noca is more like a better alternative to Authorize.net. Paypal in shopping cart takes the Consumer away from Merchant site and requires the Consumer to have an account i.e. sign-up. Even with Paypal's high userbase only 1 out of 3 or 4 users in the US have an active Paypal account. Not a good idea to potentially loose majority of Payors/Buyers simply 'cause they don't have Paypal accounts
Further, when you're a small site, I'd think it's preferable to redirect your customers to Paypal's site when they enter their billing information as it gives them confidence that it's secure. As a user myself, I would think twice before typing my CC info into a small obscure website, as I have no idea what kind of security measures they have in place (https is only one piece of the puzzle).
Hehehehe. That's what everyone says when they're getting into the payment game.
Paypal: Used it for years without any problems so far. As buyer and as seller.
Dwolla: Registered an account several weeks (months?) ago. Didn't use it since then. Today I've tried to log into my account and it seems that essentially the account has been locked and I'm required to upload a photo ID in order to get my account unlocked.
So it seems that other payment providers aren't really better than Paypal. I'm glad I don't have any money stored on Dwolla - let's see how they handle the situation.
when you enable international processing fraud rates spike (double-digit percentages in some countries) and you end up building an agressive fraud protection scheme like PayPal have
the new startups have the advantage of only serving a relatively small less risky market, and being obscure enough not to be a target of fraud groups
these new startups have nice features such as simple API's etc. but I haven't seen anything yet that is revolutionary in terms of technology that will break out of the fraud/blocking cycle
Edit: to add, I am not being dismissive of the new startups, on the contrary I am using Swipe on a new product, and I really do hope that one of these guys nails this space
Paypal are "winning" and will forever "win" because they support EVERYONE. Finding a person who can't use Paypal (who is over the age of 18 and isn't a previously terminated customer) is very hard because it supports (almost) EVERYONE yet these "new" "paypal killers" don't and they won't gain any traction because of this.
and even then there are still bigger issues, but the biggest issue is international support.
