How to verify bank details with LUCY DIAMOND?


Using the LUCY DIAMOND interface, the user sends the bank account details of the account(s) to their PSP (manually or in batch).


The bank verification request is automatically routed to the bank or PSP of the account holder in question.


Information is cross-checked within the bank’s database and a “score” is calculated based on the level of correspondence.


The scores are then sent back to the customer via the LUCY DIAMOND interface, thus avoiding any attempt of IBAN fraud.
