It's a tradeoff, for example the German Girocard network is fundamentally built on top of SEPA so it is very low cost.

But that also means that it does not support features that credit card networks support like chargebacks or 3DS. For that reason it also doesn't work online.

This is a space that a lot of bank transfer payment schemes fit into: low cost, fast settlement, high risk.
