Virtual Identifier Payment Network for Secure DDA Transactions

The patent introduces a payment network as an intermediary between the consumer's retail bank and the billing entity's commercial bank. This payment network performs verification and authentication of ACH transactions, acting as a mediator that adds security without requiring the consumer to change their existing ACH setup. The payment network validates transaction details, checks authorization, and ensures proper routing, thereby improving security while maintaining the low-cost ACH transaction structure.

The patent segments the DDA routing information into two separate components: the routing number (which identifies the bank) and the account number (which identifies the consumer's account). By processing these components separately through the payment network's verification system, the patent enables convenient payments while adding layers of security. The payment network can validate the routing number against known fraudulent patterns and verify account authorization without exposing the full account number to potential fraudsters.

The patent implements preliminary verification and authentication actions before the bulk ACH file transfer is completed. The payment network performs pre-clearance checks, validates consumer authorization, verifies billing entity credentials, and checks for fraudulent patterns before the actual fund transfer occurs. This preliminary action ensures that only verified and authorized transactions are included in the bulk file transfer, maintaining low costs while adding essential security validations.
