The ability to verify credit card numbers and account existence will be added in the next inter-banking version.


How does DIAMOND work ?



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


The 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 correspondance.


Scores are sent back to the client through the client-facing DIAMOND interface.



Results and notifications


DIAMOND returns any number of results and scoring from the verification. For example:

  • First and last name are correct (scoring)
  • Date of birth is correct (true or false)
  • Account is valid or invalid (true or false)
  • Account is open, closed, or inexistant (true or false)

Notifications can be scheduled at any point of the verification process to keep users up-to-date on their requests.
