I think that's also the case in France and Poland. Don't they have Visa and Mastercard debit cards? I can understand not having credit cards, although they are less of a hassle if they get stolen or fraud happens than a card that has direct access to your bank account, but to not have any sort of card would seem bizarre to me.
Visa and Mastercard debit cards are available here in germany, but usually for an extra fee. So most people don't want them. And our normal debit cards don't work with Amazon.com Payments (funnily enough they work with Amazon.de).
Most people here also don't have a credit card, because you just don't need one most of the time. Actually you just need one to shop online in (non-european) foreign countries. I myself didn't pledge anything on Kickstarter in the past, only because of that reason. Only when OE announced Eternity I went out of my way and ordered a prepaid credit card, but I can't see many people doing that.
So, when the Paypal option will be activated, I really would expect a spike in pledges just from germans. Sadly, these paypal donations will never appear on the Kickstarter page, as they said in their FAQ.
