In Germany we have a bank transfer based system called Giropay. As part of the purchase process after picking Giropay as the payment method you get asked what bank you're at and then get redirected to a special version of the bank site (for my bank it is giropay.normal-bank-domain.de instead of the usual www.normal-bank-domain.de) where you log in using 2FA etc as usual and proceed with the bank transfer. Once you are finished you get redirected back to the merchant. In the background, Giropay confirms your payment with the merchant so that the merchant knows she will receive the money soon. I think it's a good system. Not all banks participate in it, however.
