because nothing works like a credit card. e.g. the popular direct debit payments can be charged back very easily + you just have to search for an valid account number (= fraud).
The only payment method that works with recurring and more or less "final/instant" transactions is credit card.
So there is no alternative for SaaS or in-app-payments to credit cards (or some direct debit risk mitigation business like paypal)
in Germany, direct debit transcation currently need an account number and a bank id (BLZ). Or BIC/IBAN (see Wikipedia).
There is no validation except some nummerical tests. You can enter the number of some charity or your landlord when doing an order at e.g. Amazon.
To deal with that risk, every bank account holder has the right to chargeback transactions without giving a reason. That's why banks typically keep a lot of the money you invoice for a grace period of approx 6-8 weeks. And companies like Otto have their own credit check companies…
tl;dr if you instantly deliver items or services, direct debit is not safe.

That is... simply not true. Or perhaps I am misunderstanding what you are saying. There isn't a bank in the EU that will allow you to make a transfer from an account that's not yours (authenticated by whatever means - card readers, digipass, RSA keychain gadgets that display a new number sequence every minute, etc.).
direct debit ("Lastschrift") is kind of a reverse transaction. You tell your $own bank to collect the money from an account of your customer at $other bank
Oh right, I see, my mistake. I didn't know Amazon used this. In Belgium it's only used (afaik) by 'trusted' institutions, like utility companies. And as a customer you still need to authorize them the first time.
Charge back from credit cards works just fine, too. And using it with either banking system gets you in rather serious trouble if you're found to abuse the charge back mechanism.
Safe payment methods are advance payment (since there's no reason to allow someone to charge back an order they've explicitely placed at their bank) and cash on delivery (though that's expensive). Which is why some large merchants (eg. Neckermann) restrict payment options to these two for the first transaction.
