In EU, ASPSPs that offer to a payer a payment account that is accessible online are required to have in place at least one interface which allows AISP, PISP and CBPII access to customer data.
ASPSPs which provide access through a dedicated interface but have not received an exemption from regulatory authorities are required to have a contingency mechanism in place for TPP access.
Banks should implement contingency mechanism as a short term measure to become regulatory compliant.
In UK, FCA has mandated ASPSPs to enable TPP access via dedicated interface. ASPSP’s who are unable to obtain exemption from contingency mechanism will need to implement Contingency Mechanism/Fall back mechanism.
