How WALDO Works

​
Overview

WALDO operates by comparing the customer’s verified identity—obtained through Straddle ID—with the account ownership details retrieved from their financial institution via open banking. The algorithm employs advanced machine learning models to handle variations in data and perform accurate matching in real-time.

Bank Account Connection via Bridge

  • Customer Authentication: The customer authenticates with their financial institution using the Bridge widget.
  • Account Ownership Details Retrieval: Bridge securely retrieves the account ownership information.
