Is it? I see it more as an underwhelming fix for SEPA Direct Debit's inability to verify payment data synchronously.
* iDeal doesn't support basic features like pre-authorization. I'm not even sure if it supports setting up a payment agreement without triggering an immediate payment at all (pretty sure it didn't, when we integrated it a couple of years ago).
* It hands over the customer's IBAN, which isn't really that much safer than a credit card number, since any merchant can trigger a SEPA Direct Debit using it. While you can trigger a chargeback, that requires you to actively monitor for fraudulent transactions, which a decent system wouldn't allow in the first place.
* iDeal recurring payments are SEPA Direct Debit, with all their downsides, like taking days to confirm and a payment that fails due to insufficient funds in the customer's bank account resulting in a significant fee the merchant has to pay (and will probably pass on to the customer).
And Wero has one of the worst, least informative websites I have ever seen. So it's really hard to figure out how it works, and what it supports.
