PayPal is what’s known as an eWallet, an electronic purse.
Users must transfer money first to the PayPal account or set up a direct debit order from their bank account or credit card.
SOFORT, however, doesn’t require such detours, because it works on the basis of recognised online banking.
You don’t have to go to the effort of registering or setting up a virtual account.
This means there’s no need for additional bookkeeping.
Your online banking login details and your confirmation code are all that you need for online shopping.
