SIBS — Sociedade Interbancária de Serviços
An interbank company that owns the Multibanco network and the MB Way app. That is why every bank's cash machines in Portugal look the same and have the same menu: the banks are all connected to a shared network.
Where you come across it. Cash machines, card terminals, paying by reference, MB Way.
Any dispute about money still has to be taken up with your own bank: SIBS runs the network, but your account is with the bank.
