Abstract: In one embodiment, a method includes receiving, by a payment service system (PSS), a payment request from a payment application executing on a device of a sender. The payment request includes a recipient identifier corresponding to a recipient. The sender and recipient have financial accounts associated with the PSS. The method includes determining a similarity score based on a comparison of contact records associated with the device of the sender and contact records associated with a device of the recipient. The method includes, responsive to determining that the similarity score does not satisfy a threshold similarity score, transmitting a confirmation request to the device of the sender to confirm an identity of the recipient. The method includes receiving, from the device of the sender, an approval response to the confirmation request. The method includes, authorizing a payment transaction associated with the payment request based on the approval response.

Abstract: Disclosed herein are systems and methods for processing a payment request that use mobile devices to have money transferred. These mobile devices are capable of running a payment transfer application that facilitates a transfer of money. A user can then execute the payment transfer application using a mobile device to send money, through a payment processing system that runs the payment transfer application, to a recipient account. One or more techniques authenticate a user of the mobile device by multi factor authentication prior to processing requests for money transfer initiated by the user.
