PSD2, which is scheduled to be implemented in January 2018, will effectively end banks' monopoly on their customers' account data.
Deloitte’s 2016 report, ‘PSD2 opens the door to new market entrants’, provides a breakdown as to what the revised legislation means for both customers (Payment Service Users (PSUs)) and the banking and payments industries, stating that the most significant change proposed by PSD2 is the use of Third Party Providers (TPP), of which there are two new types: Payment Initiation Service Providers (PISPs) and Account Information Service Providers (AISPs).
