Authentication token for wallet based transactions

This invention describes a system where a mobile payment device informs its associated wallet service provider of a temporary internet address for a server running directly on the mobile device. This allows the wallet service provider to then initiate a direct connection back to the mobile device to retrieve transaction details, verify them, and confirm the user's chosen payment account, streamlining and securing mobile transactions.

Why it matters: In 2018, reliably and securely establishing a server function on a mobile device for a remote service provider to contact was challenging due to network and OS limitations. Modern mobile operating systems and secure messaging frameworks now offer more robust and standardized ways for a wallet service provider to initiate secure communication back to a specific mobile device.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
